BACKGROUND

The importance of cleanliness has long been recognized, particularly inthe fields of heath-care, food preparation, and laboratories, to namebut a few. The practice of surgical scrubbing by surgeons and otheroperating room personnel is probably the epitome of efforts to cleansethe hands and forearms of persons working in sterile environments.Although manual hand-washing can appear to be effective, medical expertshave concluded that automated hand-washing increases hand-washingcompliance and reduces the risk of infection.

Touchless automated hand-washing devices are designed to wash the handsof the user and provide the proper amount of antimicrobial solution in aset time. Additionally, these systems diminish the deterrent effects offriction and irritation associated with frequent manual hand-washing.Notwithstanding the benefits and convenience of automated washingdevices, difficulties still exist with verifying employee or staff useof the washing apparatus. Moreover, existing systems lack the ability toprovide a complete washing. It would be advantageous to have a systemthat provides automated washing that may be operable to verify usage bythe intended users. Accordingly, the present invention is directed to asystem and method for providing automated washing, which may be operableto monitor compliance with one or more hygiene requirements.

In addition to the forgoing, problems also exist with spread of bacteriaor other contagions throughout a facility based on the movement ofpersons within the facility. Accordingly, it would be desirable to havea system and/or method for tracking and enforcing hygiene requirementsthat accounts for movement of individuals associated with a facility.Moreover, it would be desirable to have a system and/or method formonitoring a plurality of hygiene protocols that are associated with aplurality of different locations or network enterprises.

In designing an automated cleaning system a number of features should beconsidered. For example, the automated cleaning system should be capableof verifying user compliance with a hygiene protocol and also capable oftracking the movements of persons associated with a facility havinghygiene requirements. Moreover, the verification system should beoperable for a plurality of washing stations associated with a pluralityof enterprise networks. Further, the verification system should includea computer readable medium having a set of processor accessible datastructures for identifying a hygiene compliance, recording and storingcompliance data, and reporting and producing a data management report(including the data collected in one or more of the enterprisenetworks). The verification system should also include an electronichygiene compliance verification data signal capable of being stored on acomputer readable medium and including source and destination addresses,hygiene compliance information (including data regarding a movement of aperson and hygiene related actions taken by the person as a consequenceof the movement), an enterprise identifier, and a compliance monitoridentifier.

When designing an automated cleaning system, a method to report hygienecompliance should also be provided. The method for reporting hygienecompliance should include determining a geographic location associatedwith a compliance monitor, determining a monitored entity identifierassociated with the geographic location information, determining hygienecompliance data, providing hygiene compliance data associated with themonitored entity identifier (including data regarding a movement of aperson and hygiene related actions taken by the person as a consequenceof the movement), determining report requirements, and forwarding theprovided hygiene compliance data to the compliance monitor.

The tag 208 is read by the RFID reader 212when the user 204 approaches and/or begins using the cleaning station100 a. When the user 204 places his or her hands into the cleaningstation washbasin 220, the optical sensor 216 initiates a cleaningcycle. If the hands of the user 204 do not stay in the washbasin 220 forthe full cycle time, the optical sensor 216 will indicate in the datastructure 332 that the user 204 did not have a complete cleaning. Oncethe user is finished using the cleaning station 100 a, the data showingsuch items as user name, time, date, station location and/oridentification, and whether the cycle was complete, etc., is stored inthe data structure 332. The stored data is later accessed by theadministration computer 104 in connection with the generation of acompliance report.

An exemplary station-use record 336 having data associated with aplurality of users 204 is shown in FIG. 4. In accordance withembodiments of the present invention, an entry in the station-use record336 may include an employee name 400 indicating who used the cleaningstation 100 a, a time stamp 404 indicating when the cleaning cycle wasinitiated, a duration 408 indicating how long the user 204 kept his orher hands in the washbasin 220, the date 412, and a compliance indicator416 specifying whether or not the user 204 kept his or her hands in thewashbasin 220 for the required time. As an example, the station-userecord shown in FIG. 4 indicates that on May 21, 2006 Janet Smith metthe hand-washing requirement by completing a cleaning cycle that wasinitiated at 8:00.00 A.M. and that lasted for 10 seconds. In analternative embodiment, the station-use record 336 may contain only rawdata such as the time 404, date 412 and duration 408 of the cleaningcycle while determinations related to compliance requirements are madeby a separate module running on the administration computer 104.

The compliance-monitoring module 316 may also operate to monitorhand-washing requirements that are specific to each employee. Someemployees may have stricter hand washing requirements than others at thesame facility. For example, a hospital emergency room may employ bothsurgeons and social workers. As can be appreciated, the surgeons will berequired to wash their hands more frequently and more thoroughly thanthe social workers. Accordingly, the compliance-monitoring module 316may access employee records to determine the type, concentration, and/oramount of cleaning fluid to be dispensed for a particular employee.Additionally, employee records may contain other hand washing compliancedata that is specific to each employee such as the amount of time and/orfrequency that an employee is required to wash his or her hands. Washingrequirements may also depend on an employee's history of compliance withhis or her washing requirements. For example, an employee may berequired to wash his or her hands more thoroughly if his or her previoushand washings were incomplete or hand not been wash for some period oftime.

Embodiments of the present invention may include a training module 320.In accordance with at least one embodiment of the present invention, thetraining module 320 operates to transmit educational information to theuser 204 while the cleaning cycle is running via sound and/or a visualsource, such as a video display 224. The information may comprisesegments equal in duration, or slightly longer or shorter in durationthan the cleaning cycle. For example, the segments may containinformation regarding hand hygiene in a series of segments lastingapproximately 10-15 seconds. In accordance with at least one embodimentof the present invention, the employee record 340 portion of the datastructure 332 keeps track of the user 204 and knows the sequence oftraining segments so each time a user 204 uses the cleaning station 100a, the next pertinent training segment will display on the video display224.

In accordance with at least one embodiment of the present invention, thetraining module 320 may access the employee record 340 to provide customdesigned content in conjunction with the user's 204 needs/requests.Accordingly, as one possible alternative to educational/trainingcontent, entertainment content specific to the user's 204 preferencesmay be displayed. Here, other information is conveyed to the user, suchas news (e.g., weather, breaking stories, current events, stock prices,etc.) and sports information. The training module 320 may, therefore,accommodate specific requests to convey information of interest to theuser. In at least one embodiment of the present invention, theinformation conveyed to the user may be anything other than informationabout a cleaning station function parameter (e.g., water pressure, soaplevel, etc.). That is, content other than information about the cleaningstation operating parameters so that the user is interested in stayingat the cleaning station for an entire wash cycle.

The training module 320 may give feedback to the user 204 through thevideo display 224, including such information as their hand-washingstatistics over a given period of time. For example the administrator ofa facility may want to encourage system usage by conveying one or morecompliance statistics, and/or informing a user 204 that the user 204 haswon a prize by having high marks for compliance with the hand-washingprotocol. Accordingly, the employee record 340 may keep track of dataassociated with user 204, and this data may be accessed by the trainingmodule 320 to inform the user 204 in real time, and/or the administratorin a subsequent report, as to compliance statistics. Additionally, thevideo display 224 may be used to provide notices, such as for upcomingmeetings and events that are pertinent to all staff or to a specificperson.

The solutions selection module 328 may determine which solution is to beused with each individual user 204. For example, one user 204 may havean allergy to the standard solution, so the system is programmed toautomatically use a different and appropriate solution when this user204 is identified through their RFID tag 208. Information related touser allergies may be contained in the employee record 340.

An exemplary employee record 340 for use in connection with both thetraining module 320 and the solutions selection module 328 is shown inFIG. 5A. In accordance with embodiments of the present invention, anentry in the employee record 340 may include the employee name 500,hand-washing 504 statistics associated with employee, current trainingsegment 508 to be viewed by the employee, the employee's preferredentertainment content 512, and/or a listing of the employee's allergies516. As an example, the employee record shown in FIG. 5A indicates thatBill Forbes is in 97% compliance with the hand-washing requirement, hascurrently viewed seven training modules, prefers to watch the news whilewashing his hands, and has an allergy to cleaning solution A.

In accordance with embodiments of the present invention, an employeerecord may include a lookup table that indicates a particular cleaningprotocol that is to be applied to a particular employee. An exemplarylookup table 520 is shown in FIG. 5B. The lookup table 520 includes aplurality of employee identifiers 524 and, for each employee identifier,a corresponding employee type indicator 528 and cleaning protocolidentifier 532. The employee identifier 524 is commonly an RFID orsuitable wirelessly readable identification code. The employee typeindicator 528 commonly references the job responsibilities and/ortitle/position of the identified employee. For example, in a caregiverapplication a “1” might refer to a nurse, a “2” to an imagingtechnician, a “3” to a doctor, and a “4” to a member of the janitorialstaff. Alternatively or in combination, the particular individuals maybe identified by a key code including a name or a job description. Thecleaning protocol identifier 532 refers to the particular cleaningprotocol to be used for the corresponding identified employee.Typically, each cleaning protocol has a corresponding set of cleaningmedium to be used, medium application duration, and wash duration. Forexample, cleaning protocol identifier “1” may require a ChlorHexidineGluconate (“CHG”) wash, a “2” either a CHG wash or alcohol towelette orwipe, and a “3” a CHG wash followed by an alcohol wipe. Examples ofother sanitizing solutions that may be used individually or collectivelyin cleaning protocol(s) include quaternary ammonium solutions. In oneconfiguration, the cleaning protocol identifier is further varied basedupon the location of the corresponding washing station, which is readilydetermined from the station identifier. A washing station in a highlyhygiene sensitive area, such as an operating room, may provide a moredemanding cleaning protocol than a station at a less hygiene sensitivearea, such as a nursing station. In some cases, the cleaning protocolidentifier may indicate that no cleaning is required. For example, thedata structures of FIG. 5B show that, for employee type “4”, theprotocol identifier has a value of “0”, or no cleaning is required.

It should be understood that the data fields associated with theexemplary employee record 340 discussed above and shown in FIG. 5A andthe lookup table 520 shown in FIG. 5B are by way of illustration and notlimitation. A particular employee record 340 may include other fieldssuch as, for example, a user's department, an auto-assigned systemidentification number, a RFID number, a user identification number, oneor more contact telephone numbers, and/or a contact email address. Ascan be appreciated, the choice of data fields used in a particularemployee record 340 will vary depending on the context and therequirements that are particular to each use of the present invention.

In accordance with embodiments of the present invention, the employeerecord 340 may be an instance of a global employee record maintainedcentrally at the administration computer 104. Accordingly, theadministration computer may periodically access and/or update aplurality of instances of employee records 340 associated with eachcleaning station 100 a-100 n in order to maintain a comprehensiveemployee record. Alternatively, at least a portion of the employee userecord 340 or data described herein as being associated with theemployee use record 340 may be stored in the RFID tag 208 worn by theuser 204. For example, a list of the user's 204 allergies may be storedin his or her RFID tag 208 and read by the RFID reader 212 when the user204 washes his or her hands.

Embodiments of the present invention may include operation of aconsumables authentication module 324 that operates to recognize when anon-authorized solution is introduced into the system. The consumablescontainer 228 and/or a receptacle or fitting associated with thecleaning station 100 a for receiving the consumables container 228 maybe mechanically designed to discourage introducing non-authorizedsolutions to the system. In accordance with embodiments of the presentinvention, the consumables container 228 includes a consumable containerRFID tag 232 that is recognized by the RFID reader 236 as an approvedsolutions container. If the consumables container 228 is withdrawn fromthe cleaning station 100 a and reinstalled, the RFID reader 236 willrecognize the tag as invalid and warn the user 204 through the videodisplay 224 and/or the administrator through the administration computer104 that this is not acceptable and potentially void the productwarranty. Alternatively, or in addition thereto, an option is availablewhere the cleaning station 100 a will stop functioning at the directionof the consumables authentication module 328 until a proper consumablescontainer 228 with a valid RFID tag 232 is inserted into the cleaningstation solution receptacle 230. In yet another possible alternativeand/or in addition to the options provided above, the known number ofdoses or applications of the consumable material may be associated witha valid RFID tag 232 and monitored by the consumables authenticationmodule 328 so that once the number of applications is reached (and thusthe consumable expended) the cleaning station 100 a cannot be used untilanother valid consumables container 228 is installed. For example, saythat one consumables container 228 contains enough cleaning fluid forapproximately 500 hand-washing cycles. Once the cleaning station 100 ahas administered approximately 500 hand-washing cycles using aparticular consumables container 228, then this container will no longerbe operable with the cleaning station 100 a. This prevents theconsumable container 228 from being removed, refilled with anon-approved cleaning fluid, and then reattached for use with thecleaning station 100 a. Such forced compliance for use of the properconsumables provides compliance regulators and/or administratorsconfidence that, for example, the approved disinfectants are beingapplied to the users 204 hands with each cleaning or use.

In addition to RFID, other methods and/or systems may be used toidentify the consumables container 228. In particular, the consumablecontainer 228 may be identified by a bar code and bar code reader.Moreover, the present invention may include modules that perform otherfunctions such as collecting and reporting maintenance data; reportinginformation on the last recorded information transfer; and/or reportingthe cleaning station's name, type, IP address and current softwareversion.

Referring now to FIG. 6, a block diagram showing components and featuresof the administration computer 104 is illustrated. Administrationcomputer 104 includes a processor 600, a memory 604 and signalinginterfaces 608 and 612 operable to communicate with external electronicand/or computational components. The first signaling interface 608operates to communicate with the cleaning stations 100 a-100 n overcommunication links 108 a-108 n, as described above. The secondsignaling interface operates to communicate with the various input 616and output 620 devices associated with the administration computer 104.The input device 616 may be, for example, a keyboard or a mouse. Theoutput device 620 may be, for example, a monitor or a printer.

The memory 604 includes a plurality of stored program applications ormodules that implement various features of a compliance monitoringsystem. In accordance with embodiments of the present invention, thememory 604 may include a data retrieval module 624, custom report module628, and a compliance monitoring module 630. Additionally, the memory604 may include data structures 632 associated with the various modules.In accordance with embodiments of the present invention, the datastructures 632 may include an employee record 636 and/or a compliancereport 640. As can be appreciated by one of skill in the art from thedisclosure herein, the memory 604 may include database structuresimplemented using suitable database software (such as SQL ServerExpress).

The data retrieval module 624 operates to retrieve data associated withcleaning stations 100 a-100 n. Such data may include data related tocleaning station usage and/or employee specific data. The data may becontained in a cleaning station-use record 336 and/or an employee record340 associated with a cleaning station 100 a-100 n. Additionally, thedata retrieval module 624 may operate to maintain a global employeerecord 636 as described above.

The custom report module 628 operates to generate the compliance report640. The compliance report is generated from data contained in eachstation-use record 336 associated with cleaning stations 100 a-100 n. Anexemplary compliance report is shown in FIG. 7. In accordance withembodiments of the present invention, an entry in the compliance report640 may include an employee name 700, time stamp 704 indicating when acleaning cycle was initiated, the date 708 of the cleaning cycle, thelocation 712 where the cleaning cycle took place, and a complianceindicator 716 specifying whether or not the user 204 met the compliancerequirement. As an example, the compliance report shown in FIG. 7indicates that on May 21, 2006 Janet Smith met the hand-washingrequirement by completing a cleaning cycle that was initiated at 8:00.00A.M at cleaning station A. As noted, compliance reports may include datapertaining to user statistics. Alternatively, or in addition to reportscomprising user statistics, reports may be generated that are directedto the consumables, such as soap and disinfectants.

The compliance report 640 may be generated at different time intervalsand may be grouped based on different criteria. For example, thecompliance report may be generated daily, weekly, monthly, yearly, etcetera. Moreover, the compliance report 640 may be generated that aregrouped by individual or station.

In accordance with embodiments of the present invention, FIG. 8 shows ablock diagram illustrating the steps of a method of monitoring acompliance requirement. Initially, at step 800 a user 204 approaches acleaning station 100 a and presents a badge having a RFID tag 208 to anRFID reader 212. At step 804 the RFID tag 208 is read and the user 204is identified. At step 808 the user's 204 name, the date, the time, andthe location of the cleaning station 100 a are recorded. At step 812 acleaning cycle is initiated when the user 204 places her or his hands inposition to be washed. During the wash cycle, at optional step 816, theuser 204 is provided with educational or entertainment content throughthe video display 224. At step 820 the wash cycle is completed and datais recorded including the duration of time the user 204 allowed his orher hands to be washed. At step 824 the transaction is completed andrecorded. At step 828, data is collected from the cleaning stations 100a-100 n over the communication links 108 a-108 n. In particular, datamay be routed to a central collection point or FTP folder. Finally, atstep 832, the collected data is used to generate a compliance report640. Additional steps associated with the method may include: monitoringproper use of consumables; warning that an improper consumablescontainer 228 has been installed; warning that a consumables container228 is empty or nearly empty based on the number of uses since beinginstalled; and warning that none or more users are failing to meetcompliance requirements.

The present invention may be operable to track movements within afacility and/or actions taken by those located at a facility. This andother hygiene protocol monitory features are achieved through theoperator of the compliance monitoring module 630. In tracking movementswithin a facility, the present invention is operable to track movementof both persons and objects. Additionally, embodiments of the presentinvention may be used to approximately track the movement of a contagionthrough a facility. In tracking the actions of those at a facility, thepresent invention is operable to track hygiene related activates thatmay lead to the introduction and/or spread of a contagion in a facility.

In location tracking, the present invention may define a hierarchicalrange of hygiene levels. Each level is assigned a number and the higherthe number the more stringent the corresponding hygiene requirements.The lowest level or level 1 may specify no particular hygienerequirements. Levels above level 1 may define progressively morestringent hygiene requirements. As can be appreciated, a particularfacility, such as for example, a food service establishment may haveonly two hygiene levels. In particular, level 1 may specify noparticular hygiene requirements and level 2 may specify that ahand-washing is required. Alternatively, level 1 could have the highesthygiene requirements and levels higher than 1 (e.g. level 2) correspondto progressively lower hygiene requirements. A facility, such as forexample, a hospital, may define higher level requirements that includemore thorough hand-washing as well as boot-washing. Additionally, higherhygiene levels may include frock hygiene requirements.

An example of a multi-level hygiene level assignment will now bedescribed with reference to FIG. 9. FIG. 9 is an illustration offacility having a number of different areas. The different areas A, B, Cand D may correspond to different rooms and/or sections of the facility.In accordance with embodiments of the present invention, different areascorrespond to different hygiene levels. For the facility shown in FIG.9, area A is assigned a hygiene level of 1, area B is assigned a hygienelevel of 2, area C is assigned a hygiene level of 3 and area D isassigned a hygiene level of 4. For example, in the instance that thefacility shown in FIG. 9 is a hospital, area A might correspond to abathroom. Similarly, area B might correspond to a waiting area, area Cmight correspond to a staging area, and area D might correspond to asurgery wing. As can appreciated, on or more doors or gates 904 providea means for passing between area. The facility shown in FIG. 9additionally includes a number of hygiene stations, such as for example,the automated cleaning station 100, shown in FIG. 2. The facility alsoincludes an administration computer 104 and a number of RFID monitoringstations.

In accordance with embodiments of the present invention, the concept ofhygiene levels may be further used to define a “hygiene status” which isassociated with a particular individual. An individual's hygiene statusis defined by two numerical values, which together indicate whether ornot the individual is in fact or potentially in violation of afacility's hygiene protocol. The first numerical value indicates thecurrent level of hygiene attained by the individual. As used herein,this numerical value is referred to as the individual's “hygieneradius.” The second numerical value indicates the minimum hygiene levelrequired by the area in which the individual is currently located. Asused herein, the second numerical value is referred to as theindividual's “working radius.” Here, it should be understood that“hygiene radius” and “working radius” do not correspond to physicaldistances. Instead, “hygiene radius” and “working radius” correspond tonumerical values that when compared with each other give an indicationof an individual's hygiene status. Specifically, when an individual'shygiene radius falls below his or her working radius, a “hygiene radiusviolation” occurs. The consequences of a hygiene radius violation aredescribed in detail below.

By way of illustration, FIG. 9 includes three individuals or persons,who are located within the facility. Person X is located in area C,person Y is located in area C and person Z is located in area D. Inaccordance with embodiments of the present invention, each of thepersons will have a hygiene status by virtue of their location andcurrent hygiene level. The above-described hygiene status scheme willnow be described with reference to persons X, Y and Z. Additionally,reference is made to FIGS. 10A-10C, which include a visualrepresentation of the hygiene status of persons X, Y and Z,respectively. Conceptually, a hygiene status in accordance withembodiments of the present invention may be understood as two radiisuperimposed on a set concentric circles, which represent the varioushygiene levels that may be defined for a particular facility. FIGS.10A-10C include four concentric circles corresponding to the fourhygiene levels defined for the exemplary facility shown in FIG. 9.

FIG. 10A shows a visual representation of the hygiene status of personX, who is shown in FIG. 9. As can be seen in FIG. 10A, person Xcurrently has a hygiene radius of 3 and a working radius of 3.Typically, it is the case that a person's hygiene level does not exceedthe hygiene level of the room in which the person is working. Moreparticularly, the hygiene radius does not typically exceed the workingradius. Compare this to FIG. 10B, which is a visual representation ofthe hygiene status of person Y. As can be seen in FIG. 10B, person Ycurrently has a hygiene radius 4 and a working radius of 3. Having ahygiene radius greater than a working radius may be only a temporarysituation. In particular, exposure to contagions, contaminants and/orother elements within the zone may occur which would degrade the hygieneradius value to 3 or more specifically, down to the current level of thezone in which person Y is located. Turning now to FIG. 10C, wherein ahygiene status for person Z is shown. The hygiene status depicted inFIG. 10C includes a hygiene radius of 2 and a working radius of 4. Thesituation depicted in FIG. 10B indicates a hygiene radius violation. Inaccordance with embodiments of the present invention, a number of sublevels may be defined with a particular hygiene level. These sub levelsare non hierarchical with respect to each other. This embodiment of thepresent invention is illustrated in FIG. 2D.

Whether or not a hygiene radius violation is tolerated, will depend onthe particular hygiene protocol implemented by a facility. Under a morestringent hygiene protocol, a hygiene radius violation may lead to ahygiene protocol violation. As used herein, a “hygiene protocolviolation” indicates that the person is out of compliance with thefacility's hygiene protocol and in embodiments of the present invention,which provide a monitoring of the facilities hygiene performance, theindividual's hygiene protocol violation will be recorded.

Within a more stringent hygiene protocol, different degrees ofstringency may be defined. For instance, a hygiene protocol violationmay occur only after a predetermined time from which a hygiene radiusoccurred. Alternatively, a hygiene radius violation may immediatelyresult in a hygiene protocol violation. In still other instances, afacility may force an individual to have the required hygiene levelprior to entry into a particular hygiene zone. Here, a hand washingstation may be provided in the near the boundary between hygiene zones.This hand-washing station may be electronically coupled to a door, whichprovides ingress into the higher-level hygiene zone, as described ingreater detail below.

In contrast to the more stringent hygiene protocols defined above, alooser hygiene protocol may be defined. Here, a hygiene radius violationmay be tolerated. In particular, a hygiene radius violation is notraised to a hygiene protocol violation. Instead, in response to ahygiene radius violation, an individual may simply be made aware of thefact that a hygiene related action is required or recommended.

Under any particular hygiene protocol, one or more action(s) may betaken to remedy a hygiene radius violation. For instance, the individualmay be instructed or required to wash his hands. Alternatively, theindividual may be instructed to wash one or more articles of clothing,such as a boot or frock. In accordance with yet another alternativeembodiment of the present invention, the individual may be locked outfrom using facility related equipment and/or a designated work stationor area. For instance, if the individual is working in a food serviceenvironment, that person's food prep station may be mechanically lockedout and/or logically (e.g. by software disable). In that regard, theindividual will be physically prevented from accessing any food items.In some instances, a warning may be given. This warning indicates to theindividual that a hygiene radius violation has been detected orencountered. The individual may then have a certain limited time toremedy the hygiene radius violation by taking such steps as washing hisor her hands. If the individual fails to address the hygiene radiusviolation, the hygiene radius violation may then be raised to a hygieneprotocol violation. In other instances, a lower than required hygieneradius will not be tolerated. Here, once a hygiene radius violationoccurs, a protocol violation will immediately occur.

In response to a hygiene radius violation, an individual may perform ahygiene related action and as a consequence have his or her hygieneradius upgraded. As a result of having his hygiene radius upgraded, itmay no longer be the case that his hygiene radius is lower than hisworking radius. Accordingly, the hygiene radius violation may becleared.

As mentioned above, a hygiene radius violation corresponds to thesituation wherein an individual's hygiene radius is below his or herworking radius. As can be appreciated, this situation can be broughtabout by changes in either an individual's hygiene radius or changes inthe individual's working radius. In some instances, a change in anindividual's working radius can impact the individual's hygiene radius.It should be noted however, that the reverse is not the case.Specifically, a change in an individual's hygiene radius will not impactthe individual's working radius. An individual's working radius simplycorresponds to the required hygiene level for the area in which he orshe is located. These concepts are explained in more detail withreference to FIG. 11A through FIG. 11D, which show a schematic of thefacility shown in FIG. 9.

As shown in FIG. 11A, person X is located in area C. As shown in thefigure, his hygiene radius is 3 and his working radius is 3. If theindividual leaves the area in which he is currently located, his hygienestatus may be affected. In FIG. 11A, there are shown two possible pathsperson X may take in leaving area C. Arrow 300 indicates leaving zone Cand entering zone D. Arrow 304 indicates leaving zone C and enteringzone B.

As shown in FIG. 11B, person X takes the path indicated by arrow 1100from the zone C into zone D. As indicated in the figure, when in zone Dthe individual's hygiene radius remains at 3, while his or her workingradius is raised to 4. This is the case because the individual had aprevious hygiene level of 3 and entered into a working area having ahygiene level of 4. Having not yet undergone or performed hygienerelated action, his hygiene radius remains constant. As his hygieneradius is now less than his working radius, which corresponds to ahygiene radius violation.

The hygiene radius violation depicted in FIG. 11B resulted from a changein an individual's working radius, with no corresponding change in hishygiene radius. As the individual crossed into a higher level hygienezone, a hygiene radius violation occurred. In particular, theindividual's working radius value was increased while his hygiene radiusremained constant, thereby resulting in a higher working radius thanhygiene radius, and consequently in a hygiene radius violation.

In FIG. 11C, person X takes the path indicated by arrow 1104 into zoneB. As zone B is at a lower hygiene level than zone C, this movement bythe person X does not involve a hygiene radius violation. As shown inFIG. 11C, person X, upon entry into zone B, has a hygiene radius of 2and a working radius of 2. The situation depicted in FIG. 11C is oneembodiment of the present invention, which corresponds to therequirement that a hygiene radius immediately be downgraded once a lowerlevel hygiene zone is entered. The requirements imposed on theindividual may vary depending on the hygiene protocol implemented by thefacility.

In FIG. 11D, person X takes the path indicated by arrow 1104 into zoneB. As shown in FIG. 11D, person X, upon entry into zone B, does not havehis hygiene radius immediately downgraded. Here, person X has a hygieneradius of 3 and a working radius of 2. The situation depicted herein isone embodiment of the present invention, which corresponds to thesituation where immediate downgrading of the hygiene radius is notrequired. As used herein, this situation is referred to a “contingentdowngrade” of a hygiene radius.

Here, the downgrading of an individual's hygiene radius value may becontingent on a number of factors. For instance, the downgrading of theindividual's hygiene radius may be dependent on the amount of time spentin a particular hygiene zone. Alternatively, downgrading of the hygieneradius may be contingent on the individual's contact with one or moreobjects located within the contamination zone.

Turning now to FIGS. 12A-12E, the concept of contingent downgrade of thehygiene radius value is further illustrated. Specifically, FIGS. 12A-12Eillustrate the concept of time dependent contingent downgrade of ahygiene radius. As shown in FIG. 12A, an individual is located in areaD. Here, the individual has a hygiene radius of 4 and a working radiusof 4. In FIG. 12B, the individual moves from area D into area B. Here,the downgrading of the individual's hygiene radius is contingent on theamount of time spent in the lower level hygiene zone. Accordingly, theindividual's hygiene radius value initially remains at 4, while hisworking radius is lowered to 2. As shown in FIG. 12C, the individualvery quickly returns to area D. Here, the individual's hygiene radiusremains at 4 upon his return to the area D. Alternatively, theindividual may decide to remain in zone B for an extended period oftime. This situation is shown in FIG. 12D. Here, the prolonged exposureto zone B results in a downgrading of the individual's hygiene radius toa value of 2, or, equivalently, to the same value as is in effect in thearea in which he is located. FIG. 12E indicates the situation where theindividual eventually returns to the area D after having been in area Bfor an extended period of time. Crossing into level 4 results in hisworking radius being raised to level 4. Having not yet performed ahygiene action, his hygiene radius value remains at level 2.Accordingly, a hygiene radius violation occurs.

It should be understood that the situation depicted in FIGS. 12A-12Ecorresponds to a looser hygiene compliance protocol. The situation isnot necessarily inappropriate, it is just an illustration of aparticular situation that may meet the needs of a particular facility.

As shown in FIGS. 13A-13C, using contingent downgrading of hygieneradius values may allow an individual to transition through a lowerlevel hygiene area, provided the individual does not remain in thatlower level hygiene area for an extended period of time. Referring toFIG. 13A, an individual can be seen located in area D. As shown in FIG.13A, the individual may take two different paths into zone C. The firstpath indicated by arrow 1300 takes the individual directly into area C.The path indicated by arrow 1304 takes the individual into the area C byway of passing through area B. As can be appreciated, the path indicatedby arrow 1300 will not result in a hygiene radius violation. Inparticular, the individual has a hygiene radius of 4 and is enteringinto a lower level hygiene area, namely a hygiene area requiring hygienelevel of 3. In contrast, the result of taking the path indicated byarrow 1304 may result in different actions being taken depending uponthe facility's hygiene compliance protocol. In particular, if contingenthygiene radius downgrading is allowed, then an individual may be allowedto transition through the area B, without adversely affecting hishygiene radius value. This situation is depicted in FIG. 13B.Alternatively, if contingent hygiene radius downgrade is not allowed,then the individual will not be allowed to transition through area Bwithout adversely affecting his hygiene radius value. This situation isdepicted in FIG. 13C. In FIG. 13B, the individual arrives in area C witha hygiene radius value of 4, and in FIG. 13C, the individual arrives inC with a hygiene radius value of 2.

The above discussions of the present invention address the situationwherein a hygiene radius downgrade and/or a hygiene radius violationoccurs as a result of movement of an individual through a facility.Monitoring of such a situation is illustrated in the flow chart shown inFIG. 14, which shows the operation of the compliance monitoring module630.

Referring now to FIG. 14, at step 1400, a hygiene status of one or moreindividuals is monitored. At step 1404, a transition between hygienezones is detected. If no detection of a transition between hygiene zonesoccurs, step 1400 again follows. If a transition between hygiene zonesoccurs, step 1408 follows.

At step 1408, the working radius of the individual who transitionedbetween hygiene zones is updated. In particular, the hygiene level forthe zone in which the individual is currently located is given as theindividual's hygiene radius.

In step 1412 which follows step 1408, a determination is made as towhether the individual's working radius is greater than his hygieneradius. If the individual's working radius is greater than his hygieneradius, step 1416 follows. Alternatively, if the individual's workingradius is not greater than his hygiene radius, step 1420 follows.

At step 1416, a hygiene radius violation occurs or is issued. At step1424, a determination is made as to whether the hygiene radius violationis tolerated. If they hygiene radius is not tolerated, step 1428follows. Alternatively, if the hygiene radius violation is tolerated,step 1432 follows.

At step 1428, a protocol violation occurs. Specifically, the hygieneradius violation is raised to the level of a protocol violation. Thismay or may not lead to a zone contamination, which is indicated in step1436 and which is discussed in greater detail below.

Turning now to step 1432, wherein the hygiene radius violation may betolerated. At step 1432, a determination is made as to whether aprotocol violation will occur in time. If no protocol violation willoccur, step 1436 follows. Here, one or more instructions may be given inorder to advise the individual of his hygiene radius violation.Alternatively, the hygiene radius violation may be recorded. Regardlessof the actions taken at step 1436, the method proceeds therefrom to step1400, where again hygiene status is monitored.

Turning now to step 1440, wherein the facility's hygiene protocolspecifies that a hygiene protocol violation will occur in time if thehygiene radius violation is not remedied. Accordingly, at step 1440 adetermination is made as to whether the hygiene radius violation hasbeen remedied. In remedying a hygiene radius violation, an individualmay undergo or perform one or more hygiene related activities such ashand-washing, boot-washing and/or frock washing. If at step 1440 thehygiene radius violation is remedied, step 1444 will follow. If, at step640, the hygiene radius violation is not remedied, step 1448 willfollow.

Referring now to step 1444, wherein the individual has remedied his orher hygiene radius violation. At step 1444, the individual's hygieneradius will be updated. In particular, as a result of the hygienerelated actions taken by the individual, his hygiene radius will beraised to an appropriate level. Following step 1444, the method willthen proceed to step 1400, wherein hygiene status is again monitored.

Turning now to step 1448, wherein an individual has not taken steps toremedy the hygiene radius violation. In step 1448, a determination ismade as to whether the allotted time for remedying the situation orremedying the hygiene radius violation has expired. If the time has notelapsed, step 1440 again follows step 1448, wherein the hygiene radiusviolation is continually monitored. If, in step 1448 the time has infact elapsed, step 1428 will follow. As described above, in step 1428, aprotocol violation occurs or is issued as a result of the protocolviolation. In step 1436, a zone contamination may occur which isdescribed in greater detail below.

Turning now to step 1420, wherein it was determined that the workingradius was not greater than the hygiene radius. At step 1420, adetermination is made as to whether the working radius is less than thehygiene radius. If the working radius is not less than the hygieneradius, step 1452 follows. At step 1452, it is the case that the hygieneradius equals the working radius or, equivalently, the individual hastransitioned across hygiene zones and that transition did not result ina change in the individual's working radius.

Step 1456 will follow step 1420 if it is the case that the workingradius is less than the hygiene radius. At step 1456, a determination ismade as to whether contingent downgrade of the hygiene radius isallowed. If contingent downgrade is not allowed, step 1460 will follow.Alternatively, if contingent downgrade is allowed, step 1464 willfollow.

In step 1460, a contingent downgrade is not allowed. In step 1460, theindividual's hygiene radius is immediately downgraded. In particular,the individual's hygiene radius is made equal to the working radius orrather the hygiene level in which the individual is located. Step 1400follows step 1460. In particular, after the hygiene radius has beendowngraded, the system continues to monitor hygiene status.

In step 1464, a contingent downgrade is allowed. At step 1464, adetermination is made as to whether the individual has moved back acrossthe hygiene boundary from where he came. If in fact the individual hasmoved back across the hygiene boundary, step 1468 follows. If theindividual remains within the current hygiene zone, step 1472 follows.

In step 1468, the individual has moved back across the hygiene boundary.In step 1468, the individual's working radius is updated accordingly. Inparticular, his working radius is assigned to the working radiusassociated with the previous hygiene zone from which he came. Followingstep 1468, the method proceeds again to step 1400 wherein a hygienestatus is monitored.

Turning to step 1472, wherein the individual has not moved back acrossthe hygiene boundary. In step 1472, which is an optional step, it isdetermined if the individual has come in contact with an object in thelower level hygiene zone. If the individual has come in contact with anobject in the lower level hygiene zone, step 1460 follows. If theindividual has not come in contact with an object in the lower levelhygiene zone, step 1476 follows.

As described above in step 1460, the individual's hygiene radius isdowngraded. Here, this downgrading of the hygiene radius is a result ofthe individual's contact with one or more objects in the lower levelhygiene zone.

Turning now to step 1467, a determination is made as to whether theallowed time has elapsed. Specifically, the allowed time is the time anindividual is allowed to remain in a lower level hygiene zone withouthis hygiene radius being downgraded. If the time has elapsed, step 1460follows. Alternatively, if the time has not elapsed, step 1464 follows.As described above, step 1460 leads to the downgrading of the hygieneradius and continued monitoring, whereas step 1464 leads to thecontinued monitoring of the individual without yet downgrading hishygiene radius.

In the above discussions, boundaries between hygiene zones areconsidered to coincide with certain walls within a facility. However, itshould be understood that the present invention does not require this tobe the case. For instance, in accordance with embodiments of the presentinvention, an individual may be considered to have crossed a boundarybetween hygiene zones when that individual moves beyond the range of aparticular RFID reader. This may be the case, for example, for a personwho is working at food prep station. Here, a RFID reader may beassociated with the food prep station and may be operable to read anRFID tag associated with the person provided that the person does notexceed a certain distance from the food prep station. FIG. 15 shows theallocation of hygiene levels for this exemplary food prep station. Asshown if FIG. 15, the area in the immediate vicinity of the food prepstation 1500, or, equivalently the range of the RFID reader 1504 isassigned to a hygiene level of 2. The entire area outside of the rangeof the RFID reader is assigned to a hygiene level of 1.

With this assignment of hygiene levels, the operation of the compliancemonitoring module 630 can be understood with reference to FIG. 14. Atstep 1400, the individual's hygiene status is monitored. With referenceto FIG. 15, this would include the individual working and/or located atthe food prep station. As described above, the individual leaves hisfood prep station and exceeds the range of the RFID reader 1500 which isassociated with the food prep station. Referring to FIG. 14, thistransition between hygiene zones is detected at step 1404. Accordingly,at step 1408, the individual's hygiene radius is updated. In particular,as he is transitioned from a hygiene zone having a level of two into ahygiene zone having a level one, his hygiene radius is changed from twoto one.

In step 1412, a determination is made as to whether his working radiusis greater than his hygiene radius. It should be noted at this pointthat as the individual came from a hygiene zone having a hygiene levelof 2, it is assumed that the individual's current hygiene radius uponcrossing the boundary between hygiene zones is 2. Accordingly, at step1412, it is determined that the individual's working radius is notgreater than his hygiene radius.

At step 1420 it is determined that the individual's working radius isless than his hygiene radius. Accordingly, step 1456 follows. At step1456, a determination is made as to whether contingent downgrading isallowed. As described above, this is not the case for the particularhygiene protocol which is in place. Accordingly, step 1460 follows. Atstep 1460, the individual's hygiene radius is downgraded. Moreparticularly, the individual's hygiene radius is assigned to the hygienelevel in which he is located. Specifically, the individual is given ahygiene radius value of 1. After step 1460, the method proceeds to 1400,wherein the individual's hygiene status is again monitored.

The monitoring continues until the point as described above wherein theindividual returns to his food prep station. Here, at step 1404, atransition between hygiene zones is again detected. Accordingly, at step1408, the individual's working radius is updated. More particularly, theindividual's hygiene radius is assigned to the hygiene level in which heis currently located. With reference to FIG. 15, this corresponds toassigning the individual a working radius of 2.

At step 1412, a determination is again made as to whether theindividual's working radius is greater than his hygiene radius. In thisinstance, it is the case that the individual's working radius is greaterthan his hygiene radius. Specifically, his working radius is at a levelof 2 and his hygiene radius is at a level of 1. Accordingly, step 1416follows.

At step 1416, a hygiene radius violation occurs. From step 1416, themethod may proceed as described above and will depend on the particularhygiene protocol in place at the facility. As is described above, thismay include giving instructions to the individual to remedy his hygienestatus and/or mechanically locking out the individual's work stationpending a hygiene related action.

The hygiene monitoring system 100 is described above mainly inconnection with a facility that defines multiple hygiene zones. However,it should be understood that the hygiene monitoring system 100 may beused in connection with a facility that defines only two hygiene zones,namely a hygienic area and a non-hygienic area. Once such facility wasdescribed in connection with FIG. 15. In the instance that only twohygiene levels are defined, a hygiene radius may be defined in terms ofboolean values rather than a range of numerical values.

In accordance with embodiments of the present invention, a hygieneradius violation may lead to a zone contamination. As used herein, a“zone contamination” refers to the situation wherein the requiredhygiene level for a particular zone has been violated. This may lead toa further downgrading of other individuals' hygiene radii who may belocated within the contaminated zone. Additionally, alerts may be issuedto require a zone remediation. In particular, the zone must be cleanedand/or disinfected prior to the removal of the alert and/or the removalof the indication of a contaminated status.

Turning now to FIG. 16A and FIG. 16B, zone contamination is illustrated.In particular, an individual who is located in area C enters into thearea D. If this transition is made without the individual raising hishygiene radius value to 4, then a zone contamination may occur. If thefacility's hygiene protocol so stipulates, this zone contamination mayoccur immediately as the individual enters into the higher level hygienearea. Alternatively, the zone contamination will occur after apredetermined amount of time has elapsed. As a result of a zonecontamination, any individuals within the contaminated zone will havetheir hygiene radius values downgraded. In this regard and as a result,each individual so downgraded will thereby encounter a hygiene radiusviolation. The facility may respond to a zone contamination in a numberof ways. In particular, a zone remediation procedure may be initiatedwherein the contaminated zone is decontaminated.

Turning now to FIGS. 17A and 17B, the concept of zone contamination isfurther illustrated. Whether or not a zone contamination occurs maydepend on the length of time in which the individual having a lower thanrequired hygiene value remains in the higher level hygiene zone. FIG.17A depicts the situation where immediate zone contamination is requiredand FIG. 17B indicates the situation when contingent zone is allowed. InFIG. 17A, the individual travels from zone C to zone B by way of zone D.Here, if the individual makes this transition in a sufficiently fastamount of time, zone contamination will not occur and individuals withinthe zone will not have their hygiene radius values downgraded.Alternatively, as depicted in FIG. 17B, if contingent zone contaminationis not allowed, the individual's transit through the zone will result inzone contamination regardless of how fast the transition occurs. Here,any individuals within the contaminated zone will have their hygieneradius values downgraded, specifically downgraded 3, or equivalently,the hygiene level of the person who caused the zone contamination.

Turning now to FIGS. 18A and 18B, as shown herein an individual carriesan object from C through zone D and into zone B. If contingent zonecontamination is allowed, this does not necessarily result in a zonecontamination. However, it may be the case that the individual leavesbehind the object in zone D, and leaves zone D to enter zone B. Here,the object which came from the level 3 area may result in a zonecontamination provided that it is left there for a sufficient amount oftime. As shown in FIG. 18B, the zone contamination results in adowngrading of individuals within the zone or individual's hygieneradiuses who are located within the zone.

The above discussions of the present invention address the situationwherein a zone contamination occurs as a result of a hygiene protocolviolation. This aspect of the present invention is summarized in theflow chart shown in FIG. 19. At step 1900, hygiene status is monitored.At step 1904, a determination is made as to whether there is a person orobject in the monitored hygiene zone having less than the requiredhygiene level. If this is not the case, step 1900 again follows. If thisis the case, step 1908 follows. In step 1908, a determination is made asto whether contingent zone contamination is allowed. If contingent zonecontamination is not allowed, step 1912 follows. If contingent zonecontamination is allowed, step 1916 follows.

Turning to step 1912, wherein contingent zone contamination is notallowed. If this is the case at step 1912, a zone contamination occurs.As a result of the zone contamination, step 1920 follows, wherein allindividuals within the contaminated zone have their hygiene radiidowngraded. Here, it is additionally noted that the facility may takeadditional steps to remediate zone contamination, specificallyinitiating procedures to cleanup and/or decontaminate the contaminatedzone.

Turning to step 1916, wherein contingent zone contamination is allowed.At step 1916, a determination is made as to whether the person or objecthas moved out of the higher-level hygiene zone. If the person has movedout of the higher level hygiene zone, step 1900 follows, wherein hygienestatus is continually monitored. If the person has not moved out of thehigher-level hygiene zone, step 1924 follows.

At step 1924, a determination is made as to whether the allotted timehas expired. Specifically, a determination is made as to whether thetime in which a person or object is permitted to remain in a higherlevel hygiene zone. If the time has expired, step 1912 follows. If thetime has not expired, step 1916 follows.

As described in detail above, at step 1912 a zone contamination occurs.Herein the zone contamination occurs as a result of the individualremaining within the higher level hygiene zone or a longer thanpermitted period of time.

Referring now to FIG. 20A-D, a situation is illustrated involvingcontingent downgrade of radius values and contingent contaminationzones. As shown in FIG. 20A, an individual is in the area D. Theindividual has a hygiene radius value of 4 and a working radius of 4. Asshown in FIG. 20B, the individual transitions into area B, here ascontingent downgrade is allowed, the individual's hygiene radius remainsat a value of 4 for a particular time. Additionally, it is noted thatthe individual's working radius is at a level 2, as he is in area B.FIG. 20C shows the situation wherein an object is moved from the area Cinto area B. Here, it may be the case then that the individual comes incontact with the object from area C but not in contact with any objectin area B in which he is presently located. Here, he may then encountera downgrade in his hygiene radius value to a value of 3 while in a zonehaving a hygiene level of 2. Accordingly, he may then be able to enterzone C from area B without encountering a hygiene radius violation whilenot being able to reenter the area D without encountering a hygieneradius violation. FIG. 20D illustrates the radius violation that occursupon entry into area D. This situation is shown to illustrate the pointthat objects may be moved into zones having lower level hygiene levelsand thereby not cause a contamination but may lead to the downgrading ofan individual's hygiene radius who has a higher level radius and isrequired by the lower hygiene level area in which he is located.

As can be appreciated from the discussion herein, a hygiene radiusviolation can lead to a protocol violation. Specifically, this may bethe case if the individual is required to remedy his hygiene radiusviolation by undergoing or performing a hygiene related action and theindividual does not comply with that requirement. Here, a protocolviolation may result from the hygiene radius violation. This in turn maylead to a zone contamination. Specifically, an individual with a lowerthan required hygiene level is located in a higher-level hygiene zone.As a result, a zone contamination may occur. As a result of the zonecontamination, individuals within the contaminated zone may then havetheir hygiene radius values downgraded. Then, as their working radiusvalues remain the same, a hygiene radius violation is encountered. Ifthe individuals having downgraded hygiene radius values enter or leavethe zone in which they are located, they may or may not enter into ahygiene zone that would result in a further violation of the hygieneprotocol.

This situation is depicted in FIGS. 21A-21D. As shown in FIG. 21A, anindividual transitions from area C into area D. As a result, a zonecontamination occurs. As a result of the zone contamination, individualswithin the zone have their hygiene radius values downgraded to 3. Asimilar but yet quite different situation is illustrated in FIG. 21C. InFIG. 21C, an individual transitions from the area A into area D. Here, amore severe contamination occurs whereby individuals within thecontaminated area have their hygiene radius values decreased to level 1.In the former situation, wherein individuals have a hygiene radius valueof 3, these individuals may transition into area C without negativeconsequences with respect to the hygiene protocol (FIG. 21B).Specifically, they are entering into a level 2 area while having ahygiene level of 3. In contrast, the latter situation, wherein theindividuals have a hygiene level of 1, these individuals may nottransition into area B without negatively impacting the facility'shygiene protocol (FIG. 21D). Specifically, as their hygiene radiusvalues are at 1, entering into a hygiene area of level 2 will result ina further hygiene radius violation. In turn, this may lead to yetanother hygiene protocol violation and additionally yet another zonecontamination.

As can be appreciated, this situation illustrated in FIG. 21D maymultiply to the point where a catastrophic facility wide protocolviolation occurs. In accordance with embodiments of the presentinvention, an individual's ID tag or other device displays his or herhygiene radius. In this way, the individual may use this knowledge ofhis hygiene radius in determining whether or not his crossing a boundarybetween hygiene zone will lead to further contamination.

A number of events as described herein may result in an individual'shygiene radius being downgraded. One such event is illustrated in FIG.11C. This particular event includes the crossing of a boundary betweenareas within the facility by the individual whose hygiene radius isdowngraded as a result of the boundary crossing. Another such situationis illustrated in FIG. 16B. This particular event involves a zonecontamination that results from an individual having a lower thanrequired hygiene level crossing a boundary between hygiene zones andthereby causing others to have their hygiene radii downgraded.Additionally, non-zone factors may lead to the downgrade of a hygieneradius. For instance, a facility may require a thorough hand washing atparticular time periods throughout the day. If an individual fails tocomply with this hand-washing requirement, his or her hygiene radius maybe downgraded. Moreover, it should be appreciated that one or moreaspects of the present invention, such as, the mechanical lockout ofwork stations, the requirement for hand washing, and the giving of handwashing advice may be done without reference to the hygiene radius andthe working radius values as described herein.

The above explanations of the present invention are given in the contextof facility that has a range of different hygiene levels. As describedabove, the different hygiene levels may be maintained using variousautomated cleaning stations. Automated cleaning stations operate todispense one or more fluids, such as water, a cleaning fluid, such assoap, and/or a disinfectant, etc., while a person's hands are placed ina washbasin. As used herein, a “washbasin” or “wash chamber” means astructure associated with the cleaning station where an appendage, suchas a hand (or foot/boot) are cleaned, such as one or more washcylinders, spray areas, pans, tubs, etc. Individuals, such as employeesof a laboratory, food service related industry, or health care facility,may be instructed to wash their hands for a minimum amount of time thathas been determined to be sufficient to provide a complete cleaning. Insituations where hand (or boot) washing is required, or because ofpersonal preferences, the user may be required to use (or otherwisedesire to use) an automated cleaning station that incorporates a washcylinder.

Referring now to FIG. 22, a close-up view of the exemplary automatedcleaning station 100 a is depicted. FIG. 22 provides a view of part ofthe exemplary automated cleaning station 100 a used by an employee whosehand 2200 is being placed in position to be washed. One wash basin 220and other components associated with the cleaning station 100 a can beseen in FIG. 22. The wash basin 220 may be associated with a driveassembly 2204 including a drive mechanism 2208 and a drive belt 2212.The drive assembly 2204 operates to rotate the wash basin 220 when theautomated cleaning station 100 a is in use. As the wash basin 220rotates, a plurality of nozzles (not shown) disposed on the interior ofthe wash basin 220 spray water and/or cleaning fluid onto the hand 2200.The wash basin 220 is interconnected to a seating assembly 2216 thatprovides the wash basin 220 with a mounting within a receiving basin2220. The receiving basin 2220 receives spent water and/or cleaningfluid that drains out of the wash basin 220 after use in connection withwashing or rinsing the hand 2200. The spent fluid then exits through thebasin drain 2222 towards the sewer or other disposal system.

FIG. 22 depicts one type of hygiene station that may be used inconnection with embodiments of the present invention. In addition, thepresent invention may employ other varieties of automated hygienestations that allow individuals to attain a variety of hygiene levels.(The various hand-hygiene stations described below may or may not beused in combination with the location tracking scheme set forth above.)For example, in a facility that defines only two hygiene levels, ahand-sink or an automated hand-washing station may be sufficient to meeta facility's needs. The following sets forth additional cleaningstations that may be used.

Embodiments of the present invention include of a hygiene station thatincludes a “scrub cylinder” having a brush disposed at the end of thewash basin or cylinder 220.

This automated cleaning stationincludes a cylinder that is long enough to deliver cleaning fluid to thehands, wrists, forearms and upper arms of person. The enlarged cylindermay be deep enough to accommodate a person having arms of above-averagelength. The cylinders shown in FIGS. 28A-C include distal end brushes.It should be understood, however, that cylinders of variable length maybe used that do not include distal end brushes.

Embodiments of the present invention include of a hygiene station thatincludes an adjustable cycle automated cleaning station. An adjustablecycle cleaning station is shown in FIG. 29. The adjustable cycleautomated cleaning station 2900 includes a range of cleaning cycles thatprovide a variety of different cleaning levels. The adjustable cycleautomated cleaning station includes control panel 2904, which can beused to apply different cleaning cycles may having different HSG or soapconcentrations, different cycle durations, etc. By allowing a user todefine different cycle parameters, a range of cleaning cycles can beachieved. Additionally, a variety of different spray patterns may beused. For example, the adjustable cycle automated cleaning station 2900may be operable to produce a pulsed spray pattern. Here, one or morepumps 2908 may be used to achieve a pulsed spray pattern. Additionally,the automated cleaning station may employ a drying cycle to provide amore thorough hygiene cycle. Here, the hands remain in the cylinder andair is forced through the cylinders and onto the hands.

The automated cleaning station shown in FIG. 29 also includes anoptional third cylinder in the form of fingertip cleaning cylinder 2912.As shown in FIG. 30, fingertip cleaning cylinder 2912 preferablycomprises a cylinder with a brush element located at its distal end forcleaning the fingertips of the user.

Embodiments of the present invention include of a hygiene station thatincludes a “surgical scrub automated cleaning station.” A surgical scrubcleaning station may include a combination of the above-describedhygiene stations. Specifically, the surgical scrub cylinder may be anenlarged cylinder and may include a nail brush at the bottom of thecylinder. Additionally, a removable nail pick may be associated with thecleaning station. The surgical scrub cylinder automated cleaning stationis operable to accommodate any variety of arm length. Here, a personmust be allowed to reach the nail brush at the bottom of the cylinder,while at same time having his or her arm sufficiently deep in thecylinder to provide coverage of the upper arms. As can be appreciated, arelatively shorter cylinder length would allow any arm length to reachthe nail brush, but not provide upper arm coverage for a longer arm.Similarly, a relatively longer cylinder would provide any arm lengthwith upper arm coverage, but not allow a relatively shorter arm to reachthe nail brush at the bottom of the cylinder.

Accordingly, the surgical scrub cylinder may employ one of a number ofdesigns that accommodate a variety of arm lengths. In one embodiment, asurgical scrub automated cleaning station 3100 includes multiplecylinders of different length, as shown in FIG. 31. The surgical scrubautomated cleaning station shown in FIG. 31 includes two small shorterlength cylinders 2800, such as the one shown in FIG. 28A; two mediumlength cylinders 2804, such as the one shown in FIG. 28B; and two largercylinders 2808, such as the one shown in FIG. 28C. The three sets ofcylinders are disposed next to each other and are each accessible at anygiven time. Additionally, the surgical scrub automated cleaning stationincludes a replaceable nail pick 3104.

Referring specifically now to FIG. 60, another alternative embodiment ofthe surgical scrub automated cleaning station having adjustabledepth/length is shown. More specifically, the surgical scrub automatedcleaning station includes a rotatable, extendible, and retractableaccordion cylinder 6000 to accommodate a variety of arm lengths. Theaccordion surgical scrub cylinder 6000 may be integrated into to theabove described hygiene stations. The accordion cylinder 6000 mayinclude an inner accordion wall 6004 and an outer accordion wall 6008.In the embodiment shown, water or other cleansing composition, such aschlorhexidine gluconate, is directed into the accordion cylinder 6000via a fluid inlet 6012. The fluid inlet 6012 may be positioned near aninner portion 6016 of the accordion cylinder 6000. One skilled in theart will appreciate that the fluid inlet may be positioned at any pointalong the length of the accordion cylinder 6000. For example, the fluidinlet may be positioned at a middle portion 6020 or outer portion 6024of the accordion cylinder 6000.

Once the fluid has passed through the fluid inlet 6012, the fluid Ftravels through the annular cavity 6028 positioned between the inneraccordion wall 6004 and the outer accordion wall 6008. The inneraccordion wall 6004 may also include a plurality of nozzles 6032. Thenozzles 6032 may be positioned along both a cylindrical section 6036 andaccordion section 6040 of the accordion cylinder 6000. The nozzles 6032may include various types of nozzles, such as straight, angled, orcanted nozzles, etc. in order to maximize cleansing and reducesplash-back. One of skill in the art will appreciate that the nozzles6032 may also be configured in many different nozzle patterns, such as alinear array or helical configuration depending on the desired flowpattern. The outer accordion wall 6008 retains the fluid and maintainsthe necessary fluid pressure inside the cylinder to compensate forcentrifugal forces and to ensure that the fluid is ejected out of thenozzles 6032 at a desired velocity.

The accordion section 6040 may be interconnected to the housing or otherportion of the surgical scrub cleaning station. The accordion section6040 of the accordion cylinder 6000 may also be made of a variety ofmaterials that are capable of repeated compressing and expanding, suchas a natural or synthetic rubber or other elastomer. The accordionsection 6040 is flexible and foldable. That is, the accordion section6040 is capable of compressing and expanding depending on thedepth/length of the accordion chamber 6000 necessary to accommodate aparticular arm length. In one embodiment, the accordion section 6040 isadapted to expand so that a user may insert and wash up to substantiallyhis or her elbows. In a preferred embodiment, the accordion section 6040is capable of allowing the accordion cylinder 6000 to expand and travelup to about 3-12 inches so that a user may wash his or her hands(including the digital, inter-digital, and webbed areas), forearms, andup to substantially the elbows.

The accordion section 6040 may be configured such that each fold 6044 ofthe accordion section 6040 has two adjacent faces, a first face 6048 anda second face 6052. In a preferred embodiment, the first face 6048 of afold 6044 does not include any nozzles and the second face 6052 of afold 6044 includes a plurality of nozzles 6032. In a more preferredembodiment, when the accordion portion 6024 is compressed the secondface 6052 is folded against the first face 6048 such that the nozzles6032 on the second face 6052 are obstructed/prohibited from ejectingfluid into the surgical scrub cylinder. However, when the accordionportion 6024 is expanded, the plurality of nozzles 6032 on the secondface 6052 are exposed and allowed to eject fluid into the surgical scrubcylinder. One skilled in the art will appreciate that any number ofdevices/mechanisms may be used to ensure that fluids do not exit fromnozzles 6032 on the accordion section 6040 when the accordion section6040 is compressed. One skilled in the art will also appreciate that anynumber of devives/mechanism may be used to ensure that fluids arepermitted to flow out of the nozzles 6032 on the accordion section 6040when the accordion section 6040 is expanded.

As the fluid travels along the length of the accordion cylinder 6000through the annular cavity 6028, fluid may be ejected into the accordioncylinder 6000 through the plurality of nozzles 6032 interconnected tothe inner accordion wall 6004.

In one embodiment, the fluid drains out of the accordion cylinder 6000via an outlet 6056. In one embodiment, the outlet 6056 is positionednear the inner portion 6016 of the accordion cylinder. In a preferredembodiment, the outlet 6056 is positioned such that the fluid exitingthe cylinder exits in a substantially vertical direction. That is, in apreferred embodiment, the fluid exiting the accordion chamber 6000 exitsapproximately orthogonal or perpendicular to a horizontal plane. Oneskilled in the art will appreciate that the outlet 6056 may beconfigured in a variety of ways, for example as a drain hole, a slot, ora valve, The outlet 6056 may also interconnect to the cleaning stationvia piping, tubing, hosing, or other means designed for the fluidconveyance in order to transport the fluid from the accordion cylinder6000 to an outlet or other fluid exit. The outlet drain may bepositioned in a variety of other positions, including those depicted inpreceding embodiments.

The surgical scrub automated cleaning station may also include a light6060 near the outer portion 6024 of the accordion cylinder 6000. Thelight 6060 illuminates the entrance of the accordion cylinder.Therefore, the accordion cylinder 6000 is visually inviting andunintimidating. In addition, the surgical scrub automated cleaningstation may also include an interior light (not shown) that illuminatesthe interior of the accordion cylinder. By illuminating the interiorportion of the accordion cylinder 6000, a user may visually inspect theinterior of the wash chamber before and/or during a wash cycle and hisor her hands and lower arms during cleaning to confirm debris removal.

The surgical scrub automated cleaning station may also include brushes(not shown) having with RFID technology such that a RFID reader mayrecognize the brush and limit the number of washings for the brush(e.g., only allow the brush to be used once), thereby insuring that asterile brush is used with every surgical scrub wash cycle.

Referring specifically now to FIG. 61, yet another alternativeembodiment of the surgical scrub automated cleaning station havingadjustable depth/length is shown. More specifically, the surgical scrubautomated cleaning station includes a telescopic cylinder 6100 that mayaccommodate a variety of arm lengths. The telescopic surgical scrubcylinder 6100 may be integrated into to the above described hygienestations. The telescopic cylinder 6100 may include an inner telescopingwall 6104 and an outer telescoping wall 6108 interconnected to an innercylindrical wall 6112 and an outer cylindrical wall 6116. In theembodiment shown, water or other cleansing composition, such aschlorhexidine gluconate, is directed into the telescoping cylinder 6100via a fluid inlet 6120. The fluid inlet 6120 may be positioned near aninner portion 6124 of the telescopic cylinder 6100. However, one ofskill in the art will appreciate that the fluid inlet 6120 may bepositioned at any point along the length of the telescopic cylinder6100. For example, the fluid inlet may be positioned at a middle portion6128 or outer portion 6132 of the telescopic cylinder 6100.

Once the fluid has passed through the fluid inlet 6120, the fluid Ftravels through the annular cavity 6136 positioned between innercylindrical wall 6112 and the outer cylindrical wall 6116 and betweenthe inner telescoping wall 6104 and the outer telescoping wall 6108. Theinner cylindrical wall 6112 and the inner telescoping wall 6104 may alsoinclude a plurality of nozzles 6140. The nozzles 6140 may be positionedalong both a cylindrical section 6144 and telescoping section 6148 ofthe telescopic cylinder 6100. The nozzles 6140 may include various typesof nozzles, such as straight, angled, or canted nozzles, etc. in orderto maximize cleansing and reduce splash-back. Moreover, one of skill inthe art will appreciate that the nozzles 6140 may also be configured inmany different nozzle patterns, such as a linear array or helicalconfiguration depending on the desired flow pattern. The outercylindrical wall 6116 and the outer telescoping wall 6108 retain thefluid and maintain the necessary fluid pressure inside the cylinder tocompensate for centrifugal forces and to ensure that the fluid isejected out of the nozzles 6140 at a desired velocity.

The telescoping section 6148 of the telescopic cylinder 6100 may beconfigured such that it is capable of repeated shortening andlengthening. That is, the telescoping section 6148 is capable of slidingout over the cylindrical section 6144 so that the length/depth of thetelescopic cylinder 6100 is lengthened/elongated. Therefore, thetelescoping cylinder 6100 is capable of having an adjustable length andaccommodating different arm lengths. In one embodiment, the telescopingsection 6148 is adapted to expand so surgeons having different armlengths may insert their hands and forearms (up to their elbows) intothe telescopic cylinder 6100 in order to wash and prepare for surgery.In a preferred embodiment, the telescoping section 6148 is capable ofallowing the telescopic cylinder 6100 to lengthen approximately 6inches. One skilled in the art will appreciate that any number ofdevices/mechanisms may be included to ensure that the cylindricalportion 6144 and the telescoping portion 6148 properly telescope andslide in and out of one another.

The telescoping section 6148 may be configured such that when thetelescopic cylinder 6100 is in an unextended or shortened position thenozzles 6140 on the telescoping section 6148 are blocked by thecylindrical section 6144. Alternatively, the telescoping section 6148may be configured such that when the telescopic cylinder 6100 is in theunextended/shortened position, the nozzles 6140 on the telescopingsection 6148 align with the nozzles on the cylindrical section 6144 sothat the nozzles 6140 on the telescoping section 6148 are not obstructedand fluid is ejected through the aligned nozzles and into the telescopiccylinder 6100.

A cross section of the annular cavity 6136 at the interface of thecylindrical portion 6144 and telescoping portion 6148 is shown in FIGS.63 and 64. The configuration assumes that a number of mating discretechannels in both the telescoping and cylindrical portions 6148 and 6144provide fluid to nozzles in both the telescoping and cylindricalportions. A sealing member 6300 may be moveably connected to the annularcavity 6136. The movable and translational sealing member 6300 isinterconnected to either the cylindrical walls or the telescoping walls.The sealing member 6300 of a preferred embodiment is capable of forminga waterproof seal, such as using a gasket at the intersection of themember 6300 and wall 6112. Thus, when the telescoping cylinder 6100telescopes (expands/compresses) the sealing member 6304 travels with atelescoping component such that the fluid is prevented from traveling tothe untelescoped portion of the telescopic cylinder 6100. The fluid flowfrom a first channel in the cylindrical portion to a mating secondchannel in the telescoping portion is denoted by the letter “F” anddirectional arrow. During movement, the size or cross-sectional area ofthe opening 6340 between the sealing member 6300 and end of the surface6108 increases or decreases with extension and retraction of thetelescoping portion, respectively. In this manner, fluid flows from thecylindrical portion 6144 to the telescoping portion 6148 notwithstandingmovement therebetween.

Referring back to FIG. 61, as the fluid “F” travels along the length ofthe telescopic cylinder 6100 through the annular cavity 6136, fluid maybe ejected into the telescopic cylinder 6100 through the plurality ofnozzles 6032 interconnected to the inner telescoping wall 6104 and innercylindrical wall 6112.

In one embodiment, the fluid drains out of the telescopic cylinder 6100via an outlet 6160. In one embodiment, the outlet 6160 is positionednear the inner portion 6120 of the telescopic cylinder. In a preferredembodiment, the outlet 6160 is positioned such that the fluid exitingthe cylinder exits in a substantially vertical direction. Moreover, oneskilled in the art will appreciate that the outlet 6160 may beconfigured as a drain hole, slot, valve, etc. The outlet 6160 may alsointerconnect to the cleaning station via piping, tubing, hosing, orother means designed for the fluid conveyance in order to transport theexiting fluid from the telescopic cylinder 6100 to an outlet or otherfluid exit.

The telescoping section 6148 may be interconnected to the housing orother portion of the surgical scrub cleaning station. In a preferredembodiment, the telescoping section 6148 may be interconnected to anextendible and retractable rubber baffle 6152 interconnected to thehousing of the surgical scrub cleaning station. The rubber baffle 6152acts as a protective device for users. The rubber baffle 6152 serves asa barrier so that a user's hands and/or forearms do not contact theinterface between the rotating telescoping cylinder and the stationarywash station. In one embodiment, the rubber baffle 6152 may also extendover some portion of the opening of the telescopic cylinder 6100 (notshown). In this embodiment, the rubble baffle 6152 acts as a splashguard and prevents fluid from escaping from the telescopic cylinder 6100and expands or contracts in width in response to expansion andcontraction of the telescopic portion 6148. Therefore, embodiments ofthe surgical scrub cylinders may include a rubber baffle 6152 to enhanceuser safety and prevent undesirable splash back.

Embodiments of the surgical scrub cleaning stations may also include adrip tray 6156. The drip tray 6156 is capable of containing any fluidescaping from a wash cylinder, such as the telescopic cylinder 6100. Thedrip tray prevents the floor from becoming wet and potentially unsafe.One of skill in the art will appreciate that ensuring the areasurrounding a hygiene station remains dry is important in a surgicalenvironment. For example, in a hospital surgery wing or emergency room,surgeons, doctors, nurses, and other hospital personnel likely need toprepare a patient for treatment quickly. As such, it is imperative thathospital personnel can quickly and readily comply with hygienerequirements (i.e. use a surgical scrub cleaning station) and move thepatient to the appropriate area without slipping or falling on a wetsurface. Fluid from the lower arm of a surgeon, for example, drains intothe drip tray at the elbow of the surgeon (when the elbow is held abovethe drip tray 6156 and the arm is bent upwardly).

The telescopic cylinder 6100 may also include a series of brushes (notshown) that can be inserted and removed from the telescopic cylinder6100 after use. The surgical scrub cleaning station may also utilizeRFID technology that allows for specific user settings and further doesnot allow a specific brush to be used more than once.

Referring now to FIG. 62, an alternative embodiment of the telescopiccylinder 6200 is shown. More specifically, the telescopic cylinder 6200telescopes in the opposite configuration than that shown in FIG. 61.That is, the inner and outer cylindrical walls 6116 and 6112 telescopeand slide over the inner and outer telescoping walls 6104 and 6108.

In addition, FIG. 62 shows an alternative fluid conveyance structure6204. The fluid conveyance structure 6204 of a telescopic cylinder isshown in a daisy-chain configuration. The fluid conveyance structure6204 of a preferred embodiment includes a fluid conveying conduit 6208.The fluid conveying conduit may include a hose, a tube, a pipe, or othersuitable device for conveying fluid. The fluid conveyance structure ofthe daisy chain configuration includes at least one fluid conveyanceconduit 6208 that is interconnected to a first set of fluid-conveyingchannels in the annulus defined by cylindrical wall 6116 and a secondset of fluid conveying channels in the annulus defined by telescopingwall 6108. Both the first and second sets of channels providepressurized fluid to the nozzles 6224. As such, the fluid is able totravel from the annular space 6220 (between the inner and outercylindrical walls 6112 and 6116), into and through the inlet fluidconveyance channel 6208, and then exit into the annular space 6216(between the inner and outer telescoping walls 6104 and 6108). Once inthe annular spaces 6220 and 6216 the fluid F may be ejected through aplurality of nozzles 6224 into the telescopic cylinder 6200. Additionallinks of the daisy chain may be provided such that additional positionsalong the length of the telescopic cylinder are interconnected. Thefluid F may exit the telescopic cylinder 6200 via an outlet 6228. Theoutlet 6228 is shown positioned at an inner portion of the telescopingcylinder 6200; however, one of skill in the art will appreciate that theoutlet 6228 may be positioned at any point along the length of thetelescoping cylinder that is capable of providing adequate drainage forthe telescopic cylinder 6200.

In a still further embodiment of the present invention, the fluidconveyance structure may be configured as a nozzle inlay in which thenozzle inlay interconnects the inner cylindrical and telescoping wallsto a plurality of nozzles. In addition to the fluid conveyancestructures discussed above, one of skill in the art will appreciate thatany suitable mechanism may be used to provide fluid to the nozzles.

With respect to any of the surgical scrub wash cylinders, the innerwalls are preferably designed to rotate about a rotational axis so thatwhen in use. In a preferred embodiment, the inner walls are capable ofrotating 360 degrees about some rotational axis. The rotation of theinner walls of a surgical scrub wash cylinder provides enhanced cleaningto the hands and forearms.

In yet another alternative embodiment, the surgical scrub automatedcleaning station includes a plurality of cylinders having differentlengths that may be rotated into position. Here, a person selects acylinder size and that cylinder is rotated into position such that itmay be accessed through the top opening in the automated cleaningstation. In this way, the surgical scrub automated cleaning station mayaccommodate any arm length.

One of skill in the art will also appreciate that embodiments of thesurgical scrub wash cylinders may be oriented the opposite directionfrom that shown in FIGS. 31 and 60-62. That is, the user may reachupwards to insert his or her hands into the wash cylinder rather thandownwards as shown. In the upward orientation, a fluid outlet or drainhole/slot may be provided at the outer portion of the wash cylinder(near the housing of the wash station). In this orientation, one skilledin the art will appreciate that a more robust splash-guard may beprovided to further ensure that an unacceptable amount of fluid does notescape from the wash cylinder.

The surgical scrub cleaning stations may be made of stainless steel.Moreover, the surgical scrub cleaning stations may be self-standing orwall mounted. In a preferred embodiment, the surgical scrub washcylinders are positioned at a pre-determined angle for ease of ingressand egress and to ensure adequate drainage. The surgical scrub washcylinders may be further positioned to minimize splash back. Dependingon the hygiene requirements imposed for a surgical scrub, the surgicalscrub cleaning stations may have single or multiple cycles of soapinjection. The surgical scrub cleaning stations may also have systemsterilization cycle after each cleaning cycle to ensure that the washcylinder is sterile before each use. The surgical scrub cleaning stationmay also include visual confirmation of the wash cycle progress.

Embodiments of the surgical scrub wash cylinders of the presentinvention may also include brushes designed specifically to clean thesubungual (or below the fingernail) portions of the hand. In a preferredembodiment, the brushes are designed to be attached and removed from theinner portion of the cylinders. In a more preferred embodiment, thebrushes are disposable to ensure that sterile brushes are used duringeach wash and the brushes are equipped with an identification system,such as RFID technology, to ensure that sterile brushes are used foreach use of the wash cylinder.

The fluid used in some embodiments of the surgical scrub wash stationsis preset to a certain temperature and controlled electronically by thewash station. In addition, the surgical scrub wash stations may providevisual injection confirmation that the soap/disinfectant/cleansingcomposition has been injected into the cylinder. Similarly, thesoap/sterile liquid may be interconnected to the surgical scrub washstations via disposable, single use soap cartridges, thus ensuring theevery user receives a sterile liquid/soap. However, in otherembodiments, the soap/sterile liquid may be interconnected to thesurgical scrub wash stations via bulk dispensing means, such as onegallon container.

Embodiments of the surgical scrub wash stations include RFID technologyfor compliance monitoring. For example, a surgical scrub wash stationmay include soap monitoring to ensure the correct soap is used and/or tosignal that a soap replacement is needed. Similarly, a surgical scrubwash station may include brush monitoring to ensure that sterile brushesare used and/or to signal that a brush replacement is necessary.

Surgical scrub wash stations of the present invention may also includeadditional options such as, seismic mounting anchors, a redundant powersource, and air curtain to minimize splash, an on-board water tank toensure consistent temperature and water supply, or water pressurecontrolled by an auxiliary pump to ensure desired efficacy.

In one configuration, the positional setting of the telescoping portionrelative to the cylindrical portion is set automatically in response tosensed user identifier, such as RFID. A processor in the cleaningstation senses the user's identifier and positions or repositionsautomatically the telescoping portion to a length that accommodates thelength of the user's lower arm. This can provide enhanced levels of userconvenience and satisfaction compared to a (completely) manuallypositioned or positionable telescoping portion. In the automatedconfiguration, the telescoping portion is positioned by a new user usingautomatic controls, the settings are saved and linked or related to theuser's profile or identifier, and the position of the telescopingportion is thereafter automatically determined using the user'sidentifier.

In addition to providing upper arm coverage and a nail brush, thesurgical scrub cylinder may employ additional features that provideenhanced or higher level hand washing. In particular, the surgical scrubcylinder may provide a drying cycle or a pulsed flow of cleaning fluid.Wash cycle parameters may be adjusted depending on the hygienerequirements. A self-cleaning cycle may be performed after each cylinderuse. The nail brush or brush may be replaced after each use. In somecases, the automated cleaning station may be automatically shut-downpending a self-cleaning or brush replacement. Automatic shut-down of thecleaning station may be imposed after each use or after a predeterminednumber of uses.

It should be appreciated that the foregoing cleaning stations can beconsidered extensions or modifications to the basic cleaning stationillustrated in FIG. 2. Accordingly, any of the above described cleaningstations may additionally include such components as RFID reader 212,for use in reading RFID tags 208; optical sensor 216; cleaning stationoperations monitor 200; and video display 224.

Referring now to FIG. 32, an exemplary sanitizer dispenser 3200 isillustrated. The sanitizer dispenser 3200 a includes a sanitizerdispenser operations monitor 200. The sanitizer dispenser operationsmonitor 200 is a computational device such as a general purposecomputer, controller, or ASIC that is operable to record data associatedwith employee use of the sanitizer dispenser 100 a and to report thedata to the administration computer 104. The sanitizer dispenseroperations monitor 200 may be incorporated into the sanitizer dispenser100 a (if an automated dispenser) or, alternatively, may be implementedas a separate computing device.

Also shown in FIG. 32 is a user 204 of the sanitizer dispenser 100 a.The user 204 may be an employee or visitor who is required to use asanitizer because of the nature of their work or the nature of thefacility. The user 204 is shown wearing a user RFID tag 208. The userRFID tag 208 is programmed by an RFID tag programming device (not shown)with information such as an employee number that, when read, uniquelyidentifies the employee. The RFID tag 208 may be incorporated into anidentification badge or bracelet worn by the user 204.

In accordance with embodiments of the present invention, the sanitizerdispenser 100 a includes an RFID reader 212. The RFID reader 212 ispositioned so as to be able to read the user RFID tag 208 when the user204 is obtaining sanitizer at a sanitizer dispenser 100 a. The RFIDreader 212 may be incorporated into the sanitizer dispenser 100 a or,alternatively, may be implemented as a stand-alone device. For example,the RFID reader 212 may be positioned adjacent to the sanitizerdispenser 100 a.

In a separate aspect of the present invention, the sanitizer dispenser100 a may optionally include a use verifier, such as an optical sensor216 positioned so as to be able to sense whether the user 204 actuallypositioned at least one of their hands for properly receiving a dose ofsanitizer. For example, a battery powered optical sensor 216 may beplaced adjacent a plunger 218 that is depressed by the user 204 toobtain sanitizer from the sanitizer dispenser 100 a. Alternatively, theoptical sensor 216 may serve as both a use verifier and as a trigger forthe sanitizer dispenser. For example, in touchless sanitizer dispensersthe optical sensors 216 serve to trigger the sanitizer dispenser todeliver a dose of sanitizer by an electric pump or atomizer. For suchsanitizer dispensers, the optical sensor 216 may also serve as theoptical sensor for monitoring the position of the user's hands andreporting to the administration computer 104 whether, and optionally forhow long, the person actually held their hand(s) to receive a dosage ofsanitizer, and thus, that the person was not just located near thesanitizer dispenser 100 a. Alternatively yet, other ways of monitoringwhether the sanitizer dispenser 100 a has been used are also within thescope of the invention. For example, as those skilled in the art willappreciate, the plunger 218 or other dispensing device associated withthe sanitizer dispenser 100 a may include a trip/cycle indicator (notshown) for registering whether the plunger 218 was actually depressed orotherwise triggered.

The RFID reader 212 and the optical sensor 216 (if present) are incommunication with sanitizer dispenser operations monitor 200, which, inturn, is operable to collect data associated with these devices. Moreparticularly, data is collected from the RFID reader 212 indicating theidentity of the user 204. Additionally, if the sanitizer dispenser 100 aincludes a use verifier, such as an optical sensor 216, data from theuse verifier is also collected by the sanitizer dispenser operationsmonitor 200. As those skilled in the art will appreciate, in addition toRFID, other magnetically, optically, and/or electronically readable useridentifiers are within the scope of the present invention. Inparticular, a user may be identified by way of a typed password, retinalscan, voice print, palm print, fingerprint, face identification, barcoding (on an employee ID), etc.

Also shown in FIG. 32 is a consumables container 228 that contains thesanitizing material, such as an alcohol gel. In accordance with at leastone embodiment of the present invention, the consumables container 228may optionally include a detachable connection to a consumablereceptacle 230 associated with the sanitizer dispenser 100 a so that theconsumable container 228 may be removed and disposed of when itscontents are expended. After the disposal of a used consumablescontainer 228, a new consumables container 228 is then attached to thesanitizer dispenser 100 a. In accordance with one or more embodiments ofthe present invention, the consumables container 228 also includes aconsumables RFID tag 232 that contains information related to theconsumable container 228. A consumables RFID reader 236 associated withthe sanitizer dispenser 100 a reads the consumables RFID tag 232 andcommunicates information related to the consumables container 228 to thesanitizer dispenser operations monitor 200. In one embodiment of thepresent invention, the RFID reader 212 can also serve as the consumablesRFID reader 236 so that two separate readers are not need. However, twoseparate readers could be used. In addition, although RFID is discussedherein for use of identification of consumables, as noted herein othertypes of identification systems may be used, such as bar codes. Thus,for example, if RFID is used to identify the user, and a bar code isused to identify the consumables, or vice-versa, two separate readersmay be needed.

Another example of a higher-level hygiene station that may be used isthe “complete hand care” automated cleaning station 3300, shown in FIG.33. The complete hand care automated cleaning station includes at leastthree elements that provide a total hand care package. First, thecomplete hand care cleaning station includes an automated hand-washingcylinder 220. Second, the complete hand care cleaning station includes amonitored hand-sanitizer 3200. Third, the complete hand care cleaningstation includes a monitored lotion dispenser 3300. Here, the automatedhand-washing cylinder 220 may be used to provide an initial handwashing. The monitored hand sanitizer 3200 may then be used throughoutthe day in order to maintain hand hygiene. As hand sanitizers 3200 aretypically alcohol based, the lotion dispenser 3300 is provided. Here,the lotion may be used to prevent damage to the skin, which may becaused by the use of the alcohol based hand sanitizer. Overuse oflotion, however, may be detrimental to hand hygiene. In particular,repeated use of lotion may result in the build up of a film on thesurface of the hands. This film may in fact promote the growth of germsand/or microbes. In order to prevent this from occurring, the automatedcleaning cylinder 200 may be used to thoroughly clean the hands,including washing away any film built-up due to lotion use. Here, theuse of the automated cleaning station, the hand-sanitizer 3200 and thelotion dispenser may be monitored, and instructions and/or requirementsmay be issued regarding their use. In particular, an individual may beinstructed or required to use the lotion dispenser after a predeterminednumber of uses of the hand sanitizer 3200. In addition, an individualmay be instructed or required to use the automated cleaning cylinderafter a predetermined number of uses of the lotion dispenser 3300.

Any of the above described automated cleaning stations may be used toprevent the false indication of compliance with a hygiene requirement.In particular, an automated cleaning stations may be used to ensure thathand washing in fact takes place. In contrast to automated cleaningstations, existing hand-sink monitoring systems may register that a handwashing took place when in fact none took place. For instance, existinghand-sink monitoring systems may register a complete hand wash after afaucet has been turned on for a predetermined amount of time. Here,hand-washing requirements may be easily falsified by a user simplyturning on the faucet for the predetermined time and not placing his orher hands under the faucet. In contrast, an automated hand-washingstation in accordance with embodiments of the present invention isoperable to ensure or guarantee that a hand washing actually takesplace. In particular, when the user places his or hands in the cylinder220 an optical signal (e.g., light beam) is broken. As will beappreciated other radiation wavelengths may be used to detect thepresence of the user's hands. For example, infra red sensors may be usedto detect the thermal emissions of the user's hands. As a result, theautomated cleaning cycle is initiated. The cleaning cycle continuesprovided that the signal remains broken (i.e. the hands remain in thecylinders). When the cleaning cycle is completed, it can be ensured thatthe hands were in the cylinders throughout the entire duration of thecleaning cycle. In this way, falsification of hand-washing requirementsis prevented. This aspect of the present invention is diagrammed in theflow chart given in FIG. 34.

At step 3400, a detection of a broken optical signal is made. Inparticular, as the individual places his hands within the cylinders ofthe automated washing station, the individual's hands break an opticalsignal associated with the hygiene cylinders. After the broken opticalsignal is detected, step 3404 follows. In step 3404, a wash signal isgenerated and the hygiene cycle is initiated.

Step 3408 follows step 3404. In step 3408, a determination is made as towhether the wash cycle is complete. More particularly, a determinationis made as to whether the required time has elapsed for the wash cycleto complete. If the wash cycle has allowed to complete, step 3412follows. If the wash cycle is not yet finished, step 3416 follows.

In step 3412, the wash cycle is allowed to end. Herein the individualmay remove his hands from the wash cylinders and a complete wash cycleis registered. In step 3416, wherein the wash cycle is not yet complete,the optical signal is continually monitored. If, in step 3416, it isdetermined that the wash signal is broken (i.e., the optical signal isrestored) for at least a predetermined period of time, the methodcontinues to step 3420. If the wash signal is restored (i.e., theoptical signal is broken again) before the predetermined configurabletime has elapsed, the removal of the user's hands from the opticalsignal path is deemed to be accidental or incidental and the wash is notdetermined to be compromised. The predetermined time preferably rangesfrom about 0.5 seconds to 5 seconds, and more preferably from about 0.5seconds to about 3 seconds. Stated another way, the predetermined timeranges from about 5 percent to about 50 percent of the wash duration,and more preferably from about 5 percent to about 30 percent of the washduration. In step 3420, it is determined that the individual has removedhis hands from the wash cylinder prior to the end of a complete washcycle. Herein a complete wash cycle is not registered and step 3400follows, wherein the signal is again detected in preparation for a newwash cycle.

If in step 3416 the signal remains broken, step 3404 follows, whereinthe wash cycle continues.

The deployment of various types of hygiene stations throughout afacility is illustrated in FIG. 35. Keeping with the example set forthabove, the facility shown in FIG. 35 is considered to be hospital. Here,area A (hygiene level of 1) might correspond to a bathroom. Similarly,area B (hygiene level of 2) might correspond to a waiting area, area C(hygiene level of 3) might correspond to a staging area, and area D(hygiene level of 4) might correspond to a surgery wing. Here, door 3500separates area C from area D. Door 3504 separates area B from area C.Door 3508 separates area B from area A. In implementing a hygieneprotocol and/or in maintaining the hygiene levels set forth above, oneor more hygiene stations may be strategically placed throughout thefacility. For example, a surgical scrub hygiene station 3512 may bedeployed near the door 3500 that leads into the surgery wing (area D). Acomplete hand care hygiene station 3516 may be deployed a centrallocation in the staging area (area C).

In accordance with embodiments of the present invention, an automatedcleaning station may be electronically coupled to a locking mechanism ona door, gate, turnstile, or other means for preventing ingress andegress. This aspect of the present invention is illustrated withreference to the surgical scrub hygiene station 3512 which iselectronically coupled to a locking mechanism on the door 3508. Here, aperson may be physically prevented from passing through the door 3508,if the person has not yet completed a verified wash cycle. In this way,it is ensured that an individual must have the required level radiusbefore that individual enters the higher-level hygiene area. Inparticular, the person must place his or her hands within the scrubcylinders for the duration of complete wash cycle. After the wash cycleis completed, a signal may be sent to the door 3508, which causes thedoor to unlock allowing the person to pass through. As explained inconnection with the verification cycle diagramed in FIG. 34, the use ofan automated hygiene station in accordance with embodiments of thepresent invention prevents falsification and ensures that a hand washingactually takes place. Embodiments of the present invention include anemergency override that will disable to door locking mechanism.

In electronically coupling a hygiene station to a door, it may be thecase that ingress or egress is prevented only at a certain time or inresponse to a certain event. Still referring to FIG. 35, it may be thecase that ingress into the surgery wing is prevented pending a hygieneaction only at the beginning of a shift. Here, individuals would beforced to initially perform a thorough hygiene scrub. Thereafter orthroughout the remainder of the shift, individuals may be allowed tofreely pass through the door 3500, between the surgery wing (area D) andthe staging area (area C). This free passing may be made contingent onother factors. For example, free passage through the door 3500 may becontingent on the person not leaving the staging area C and going into alower level hygiene area, namely the waiting room (area B). In addition,free passage through the door may be contingent on continued actionsthat would maintain a hygiene level. For example, use of the completehand care station 3516.

In accordance with embodiments of the present invention, the hygienerequirements associated with an individual may depend on his or jobtitle. In the hospital example give above, a surgeon may have differenthygiene requirements from that of a social worker. Moreover, hygienerequirement may be imposed on or required of workers associated with afacility and not with visitors to the facility.

An embodiment of the present invention, which employs both jobtitle/visitor specific hygiene requirements and ingress/egressprevention, will now be described with continuing reference to FIG. 35.As shown in FIG. 35, the hospital facility includes an additionalhygiene station 3520 in the bathroom (area A). The hygiene station 3520may be electronically coupled to the door 3508 in order to physicallyprevent certain individuals from leaving the bathroom if they have notundergone a verified hygiene cycle. For example, if a surgeon uses thebathroom (area A) he or she may be physically prevented from leaving thebathroom pending a verified hygiene cycle. As can be appreciated, itwould be desirable to only physically prevent certain individuals fromleaving the bathroom. In particular, if visitors to the hospital were touse the bathroom it may not be desirable to physically prevent them fromleaving the bathroom if they have not undergone a hygiene cycle. FIG. 36shows a flow chart, which illustrates this aspect of the presentinvention.

In step 3600, an individual approaches an automated hand hygiene stationor automated cleaning station and his or her RFID tag is read. Step 3604follows 3600. At step 3604, the automated hygiene station downloads aprofile specific to the user. At step 3608, a determination is made asto whether a hand wash is needed for this particular individual. If nohand wash is needed, the method continues to step 3612. At step 3612,the door is activated and the individual is allowed to pass through thedoor. This may correspond to the instance where the individual who hasapproached the hygiene station and door is a visitor to the facility.Herein the individual is not required by the facility to undergo anyhand washing. Accordingly, the individual is allowed to pass through thedoor without having to undergo a verified hygiene cycle.

Step 3612 will follow step 3608 if it is determined that the individualrequires a hand wash or other hygiene related action. At step 3612, adetermination is made as to what type of wash is needed. Here the typeof wash may be specific to the individual as indicated by his or herdownloaded profile. Specifically, for certain individuals a higher levelor more thorough hygiene cycle may be required. As described above, thismay be the case in a hospital facility when the individual is a surgeon.Alternatively, a low level hygiene cycle may be required for in thisexample a social worker.

Following step 3612, the hand washing station is configured at step3616. Step 3620 follows step 3616. At step 3620, the hygiene cycle isactivated. Step 3624 follows step 3620. At step 3624, the completion ofthe hygiene cycle is confirmed. In particular, the hygiene stationensures that a wash was completed according to the steps set forth inthe method illustrated in FIG. 19. If at step 3624 it is determined thatthe washing cycle was incomplete, step 3628 follows. At step 3628 theuser is thereby notified that his or her washing cycle was incomplete.At this time, the door is not activated and the individual is notpermitted to pass through. Accordingly, step 3620 follows step 3628wherein a new hygiene cycle is initiated.

If at step 3624, it is determined that a complete wash cycle in facttook place, step 3612 follows. At step 3612 as described above, the dooris activated and the individual is allowed to pass there through.

The present invention may be used in a wide variety of facilities, whichmay have different hygiene related requirements and/or needs. Inaddition, the present invention allows a particular facility to defineand establish hygiene protocols that are specific to the facility. Usingone or more of the aspects of the present invention set forth above, ahygiene protocol may be defined for a particular facility. Data may becollected in connection with monitoring of compliance with the hygieneprotocol. The collected data may be complied for internal use only.Alternatively, the collected data may be provided to outside reportingagencies or other third parties.

Depending on the needs of a particular facility, the present inventionallows for the implementation of a spectrum of hygiene protocols, fromthe loose to the more robust. For example, a loose hygiene protocolmight allow individuals who have not meet a hygiene requirement to movethrough the facility. A more robust protocol might instruct such anindividual to perform a hygiene related action and register a protocolviolation if the individual fails to comply with the instruction. Astill more robust protocol may physically prevent movement of anindividual past a choke point if the individual has not complied with ahygiene requirement. A particular protocol may impose hygienerequirements on visitors to a facility that differ from those that workat the facility. For those that work at a particular facility, differenthygiene requirements may be imposed based on job title.

In implementing a particular hygiene protocol, a facility may considervarious factors described herein when determining the followingparameters. In particular, a particular protocol may specify if hygieneradius violations are tolerated, whether contingent hygiene radiusdowngrading is allowed, and/or whether contingent zone contamination isallowed. Moreover, the facility's hygiene protocol may specify a timefrom a hygiene radius violation to a hygiene protocol violation. Second,the hygiene protocol may specify a time from a protocol violation to azone contamination. Additionally, the protocol may specify the time in alower level hygiene zone sufficient to cause a hygiene radius downgrade.Additionally, the protocol may specify the frequency of hand washing tomaintain a particular hygiene radius value. A spectrum of differenthygiene protocols may be implemented by a particular facility. Somehygiene protocols may employ location tracking as described herein.Moreover, it should be appreciated that a hygiene protocol may beestablished without reference to location tracking. Any hygienecompliance means as set forth herein may be used in establishing ahygiene protocol.

Referring now to FIG. 37, an exemplary multilevel hygiene protocol isgenerally identified by reference number 3700. For each hygiene level, anumber of parameters are specified. For the exemplary hygiene protocol3700 illustrated in FIG. 37, the following parameters are defined:hygiene requirements 3704, response to hygiene radius violation 3708,time to hygiene protocol violation 3712, allowability of contingent zonecontamination 3716, time to zone contamination 3720, and response tozone contamination 3724. The hygiene protocol 3700 illustrated in FIG.37 defines a series of hygiene levels with hygiene level 1 being thelowest level.

Hygiene level 1 indicated by reference number 3728 specifies noparticular hygiene requirements. Accordingly, the hygiene parameters3708 through 3724 are not applicable. Hygiene level 2, indicated byreference number 3732, includes more stringent hygiene requirements thanhygiene level 1, indicated by reference number 3728.

Hygiene level 2 (3732) specifies that an alarm is given as a response toa hygiene radius violation. The time to hygiene protocol violation isone minute and contingent zone contamination is allowed. At hygienelevel 2, zone contamination does not occur. Accordingly, no particulartime is specified for a time to zone contamination, and no particularresponse is specified for a zone contamination.

Hygiene level 3 (3736) specifies more stringent hygiene requirementsthan hygiene level 2 (3732). In hygiene level 3 (3736), an alarm isgiven in response to a hygiene radius violation. A quicker time, namely,30 seconds, is specified for a time to hygiene protocol violation. Athygiene level 3, contingent zone contamination is allowed. However, incontrast to level 2 (3732), one minute is specified for a time to zonecontamination. In response to a zone contamination, hygiene level 3(3736) specifies an alarm.

Hygiene level 4 (3740) specifies more stringent hygiene requirementsthan hygiene level 3 (3736). In hygiene level 4 (3740), an alarm isindicated in response to a hygiene radius violation. Zero seconds isspecified as a time to hygiene protocol violation. Accordingly, ahygiene protocol violation occurs immediately following a hygiene radiusviolation. At hygiene level 4 (3740), contingent zone contamination isnot allowed. Accordingly, zone contamination occurs immediatelyfollowing a hygiene protocol violation. In particular, zero seconds isspecified as the time to zone contamination. In response to the zonecontamination, hygiene level 4 (3740) specifies an alarm and mechanicallockout workstations and/or doors that provide access to a particulararea.

Turning now to FIG. 38, an exemplary multilevel hygiene protocol isgenerally referred to with reference number 3800. Hygiene protocol 3800includes protocol identifier 3804 that allows multiple hygiene protocolsto be defined for a particular hygiene level. A hygiene level mayinclude different requirements depending on, for example, an employeetype, job title, whether the monitored individual is an employee or avisitor to the facility, and any other requirement that specifies orrequires individuals to have different hygiene requirements for aparticular hygiene level. The remainder of the hygiene protocolparameters remain the same as the hygiene protocol 3700 shown in FIG.37. For some hygiene levels in the hygiene protocol 3800, the hygienerequirements do not differ based on the protocol identifier 3804. Morespecifically, hygiene level 1 specifies requirements 3808 a for protocolidentifier 1 and requirements 3808 b for protocol identifier 2 which areexactly the same. In particular, as hygiene level 1 is the leaststringent hygiene level, no particular hygiene requirements arespecified. Similarly, hygiene level 4, the most stringent hygiene level,requires the same hygiene requirements for each protocol identifier.Specifically, both hygiene level requirements 3820 a for protocolidentifier 1 and hygiene level 4 requirements 3820 b for protocolidentifier 2 specify an alarm given in response to a hygiene radiusviolation; zero seconds is the time to hygiene protocol violation;contingent zone contamination is not allowed; zero seconds to zonecontamination; and alarm and lockout as a response to zonecontamination. Turning now to hygiene level 2, the second most stringenthygiene requirement level, a hygiene requirement 3812 a is specified forprotocol identifier 1, and a hygiene level 2 requirement 3812 b isspecified for protocol identifier 2. For protocol identifier 2, level 1specifies a one minute to hygiene protocol violation. For protocolidentifier 2, level specifies no particular time to hygiene protocolviolation. In this way, different hygiene requirements may be associatedwith different individuals. For example, an employee may be assignedprotocol identifier 1, whereas a visitor may be assigned protocolidentifier 2.

Turning now to FIG. 39, an exemplary hygiene compliance report isgenerally referred to with reference number 3900. The compliance report3900 is compiled by the operation of the compliance monitoring module630 based on a particular hygiene protocol. In particular, thecompliance monitoring module 630 may implement a hygiene protocol, andin so doing produce a compliance report such as the compliance report3900, shown in FIG. 39. For example, exemplary hygiene protocols 3700 or3800 may be used to compile a hygiene compliance report 3900. Theexemplary hygiene compliance report 3900 shown in FIG. 39 includes anumber of parameters. Each entry in the hygiene compliance report 3900specifies an entry that records an employee or visitor's transitionacross a hygiene boundary, which is recorded as hygiene complianceparameter 3902. Hygiene compliance report 3900 records transitions thatoccur from a lower level hygiene zone into a higher level hygiene zone.Compliance report 3900 may be provided in connection with the hygienecompliance 4000, shown in FIG. 40, which specifies transitions whichoccurred from a higher hygiene zone into a lower level hygiene zone.Compliance report 3900 and compliance report 4000 are shown separatelyfor illustration purposes. It should be understood that these reportsmay be combined to provide a composite report that records all hygienerelated events.

Turning first to hygiene compliance report 3900, the parameters includean employee ID 3904, a time in which the transition occurred 3908, adate 3912 which the transition occurred 3912, a hygiene radius value3916 assigned to the individual when the individual transitioned acrosshygiene boundaries, whether a hygiene radius violation occurred 3920,the time to hygiene radius violation remediation 3924, whether aprotocol violation occurred 3928, and whether a zone contaminationoccurred 3932. The hygiene compliance report 3900 records a number ofhygiene zone boundary transitions 3936 a through 3936 g. Turning now tothe compliance report 4000, which specifies hygiene boundary transitionsthat occurred from higher hygiene level to a lower hygiene level.Parameters associated with compliance report 4000 include an employee ID3904, a time of day 3808, a date 3912, a hygiene radius during thetransition 3916, whether a hygiene radius downgrade occurred 4004, and atime to hygiene radius downgrade 4008. The hygiene compliance report4000 includes a number of entries 4012 a-4012 i that record hygiene zoneboundary transitions. The hygiene zone boundary transitions recorded incompliance reports 3900 and 4000 are described and illustrated abovewith reference to FIGS. 11A-21D.

FIG. 41 illustrates yet another compliance report 4100 that may beproduced by the operation of the compliance monitor 630. The hygienecompliance report 4100 includes a listing of hygiene radius violationsthat occurred during a particular day, including the results of thesehygiene radius violations. In the exemplary hygiene compliance report4100, six hygiene radius violations, 4104 a-4104 f occurred. For eachhygiene radius violation 4104 a-4104 f, the hygiene compliance report4100 specifies a hygiene radius violation number 4108, an employee ID4112, a cause of the hygiene radius violation 4116, a time that thehygiene radius violation occurred 4120, a date which the hygiene radiusviolation occurred 4124, a time to hygiene radius violation remediation4128, and whether or not a hygiene protocol violation occurred 4132.Hygiene radius violations 1-5 (4104 a-4104 e) record the hygiene radiusviolations that are specified in compliance report 3900. Compliancereport 4100 additionally includes a hygiene radius violation 4104 f thatoccurred as a result of a zone contamination.

Embodiments of the present invention are directed to a compliance systemand monitoring method used in connection with the complete hand caresystem shown in FIG. 33. FIG. 42 is a flow chart that illustrates acompliance monitoring method used in connection with the complete handcare station 3300. The method 4200 illustrated in FIG. 42 may be used toimplement a particular hygiene protocol such as hygiene protocol 4300illustrated in FIG. 43. Hygiene protocol 4300 includes requirements fordaily hand washing, lotion use and mandatory complete hand washing.Parameters specified by the hygiene protocol 4300 include a hygienerequirement 4304, a frequency of the hygiene protocol requirement 4308,and a hygiene station component 4312 that is used to implement thehygiene requirement 4304. The first hygiene requirement 4316 is directedto a daily hand washing requirement. In particular, the hygiene protocol4300 specifies (hygiene requirement 4304) a particular number (frequency4308) of washes that must be achieved during a particular day. The dailywashes may be implemented with the hygiene wash chamber 220 or the handsanitizer 3200 as specified by hygiene station component parameter 4312.The next hygiene protocol requirement 4320 specifies that lotion must beused after every use of the hand sanitizer. Here, the lotion dispenser3300 may be used to accomplish the hygiene requirement 4320. The nexthygiene requirement 4324 specifies that a complete hand wash must beachieved after a predetermined number of uses of the lotion dispenser3300. Here, the wash chamber only 220 must be used to carry out thehygiene requirement 4324. This set of hygiene requirements may bemonitored using the method specified in FIG. 42.

Turning initially to step 4204, usage of the complete hand washingstation 3300 is monitored. In step 4204, a type of hygiene station usageis determined. As there are three different hand station components, ifthe wash chamber 2200 is used, step 4208 follows. If the hand sanitizeris used, step 4212 follows. If the lotion dispenser is used, step 4216follows. At step 4208, the usage of the wash chamber is recorded and themethod proceeds again to step 4204. In step 4212, the use of handsanitizer is recorded. At step 4216, an instruction is provided to theuser indicating the need for lotion use. At step 4220, if the lotion isnot used within a predetermined time, non-usage of the lotion dispenseris recorded. Step 4204 follows step 4220. At step 4216, use of thelotion dispenser is recorded. Following step 4216, a determination ismade of the prior use history of the wash chamber at step 4224. At step4228, a determination is made if a complete wash cycle is needed. If nowash cycle is needed, step 4204 follows step 4228. If a wash cycle isneeded, step 4232 follows, which includes providing instructions to theuser for usage of the wash chamber. At step 4236, if the wash chamber isnot used within a predetermined time, recordation of the non-usage ofthe wash chamber is recorded and control passes again to step 4204.

In implementing the method 4200 shown in FIG. 42, the compliance monitor630 may produce the compliance report 4400 shown in FIG. 44. Thecompliance report 4400 includes entries 4432 a-4432 s that recordparticular usages of the complete hygiene station 3300. For each entryin the compliance report 4400, the following components are specified:an employee ID 4404, a usage type 4408, a date 4412, a time 4416, anindication of compliance with daily requirements 4420, an indication ofcompliance with lotion use requirement 4428, and an indication withcompliance of mandatory chamber use 4428. The compliance report 4400shows compliance statistics for a single employee. It should beunderstood however, that compliance report 4400 may include compliancestatistics for any number of employees. For the employees' compliancestatistics shown in compliance report 4400, it can be seen that on afirst day, the individual was out of compliance with daily washingrequirements. On the second day, the individual was out of compliancewith the lotion use requirement, and on the third day, the individualwas out of compliance with the mandatory wash chamber use requirement.

The compliance reports 640, 3900, 4000, 4100 and 4400 described hereininclude raw compliance statistics. In accordance with alternativeembodiments of the present invention, compliance statistics may beanalyzed and organized and presented in a compliance report thatincludes charts and/or graphs. An exemplary trend chart or bar graphcompliance report 4500 is shown in FIG. 45. The bar graph 4500 showscompliance statistics for various time periods 4504 a-4504 e. For eachtime period, the compliance report 4500 includes an indication of thetarget compliance measurement 4508 in a side by side comparison withactual compliance statistics 4512. For the compliance report 4500, inthe time period 4504 a, it can be seen that the actual compliancestatistics 4512 exceeded the target values 4508.

FIG. 46 shows a line graph 4600 showing compliance statistics for acardiology department. The compliance report 4600 includes a line 4604indicating the data points for actual wash counts on consecutive days.The compliance report 4600 additionally includes a line 4608 showing thetarget washes for each of the consecutive days. Additionally, FIG. 46includes an indication 4612 of an outbreak which occurred between days 8and 10.

In accordance with embodiments of the present invention, real timefeedback may be provided to an employee in order to improve hygieneprotocol compliance. This real time feedback may be provided through acomputational device and displayed in a graphical user interface. Thegraphical user interface may be displayed on a screen such as displayscreen 224 associated with a particular hand hygiene station. Inaccordance with alternative embodiments of the present invention, thegraphical user interface may be provided on a screen associated with acomputational device that is a stand alone device and providedseparately from a particular hand hygiene station.

FIG. 47 shows an exemplary graphical user interface 4700. The graphicaluser interface 4700 includes a schematic layout of the facility in whichmonitored employees and/or visitors are located. The facility map 4704includes icons 4708 that represent individuals and the individual'slocation within the facility. The icons 4708 may be accessed by a userwho clicks on the icon using the mouse and associated mouse cursor 4712.In response, the graphical user interface may provide a drop down menu4716 that includes current hygiene status information for the individualwhose icon was accessed. The drop down menu 4716 includes hygieneinformation such as an employee ID 4720, a current working radius 4724,a current radius 4728, an indication if a hygiene radius violation hasoccurred 4732, and a current time to hygiene protocol violation 4736.These statistics may be used in order to allow the individual toremediate his deficient hygiene status as appropriate.

In another embodiment, a web-enabled hygiene monitoring system isprovided. As shown in FIGS. 48A-B, the system 4800 includes a pluralityof discrete monitored entities 4804 a,b-w, each comprising first,second, . . . xth; first, second, . . . yth; or first, second, . . . jthwashing stations 100 a-x, 100 a-y or 100 a-j, respectively, a compliancedata hub 4812, a compliance monitor 4816 a,b-p, and a compliance filter4820, all interconnected by a data network 4824.

The entities 4804 a,b-w are each a monitored location. Particularmonitored entities may be discrete facilities of a common monitoredenterprise. For example, the automated compliance data hub 4812 maymonitor a network of hospitals or restaurants. In one configuration, thecompliance data hub 4812 processes and analyzes data received from thevarious locations, prepares reports, and provides user and administratorcompliance feedback. Referring to FIG. 48A, the monitored entities 4804a and 4804 b represent different locations associated with a commonbusiness enterprise 4806. Alternatively, a monitored enterprise mayinclude only one monitored entity. In FIG. 48A, monitored entity 4804 wrepresents a separate business enterprise. In other words, thecompliance data hub 4812 may be associated with a plurality of businessenterprises that are owned and operated by different companies, and oneor more of those enterprises may include a plurality of differentlocations or facilities. Examples of enterprises include health careproviders, food service providers (e.g., restaurants), food and/or drinkmanufacturers (e.g., meat packing plants, dairy product manufacturers,and the like), and other types of providers subject to internal and/orregulatory cleaning requirements.

In accordance with embodiments of the present invention, each monitoredentity 4804 network includes an administration computer 104 a,b-w ordata collection point that collects cleaning information from eachwashing station 100 a-x, a-y, a-j in the corresponding enterprisenetwork and, periodically or continually, provides the information tothe compliance server 4832 (shown in FIG. 48B) of the compliance datahub 4812. As can be appreciated, an administration computer may be anetwork computer or server and may include a database. In thisconfiguration, the cleaning information may be pushed by theadministration computer 104 a,b-w to the compliance server 4832 orpulled from the administration computer 104 a,b-w by the complianceserver 4832. Furthermore, it is noted that configuration of the eachmonitored entity 4804 a,b-w substantially corresponds to the embodimentof the present invention shown in FIG. 1.

Each administration computer 104 a,b-w may include a user interfacethrough which employee related data may be entered. The user interfacemay be implemented using any suitable software package (such as Access2003) and can include portions that are icon driven to facilitate dataentry and include drop down menus to ensure consistency of data.Additionally, data may be dynamically saved when possible. The userinterface may include a plurality of screens wherein data is saved aftera screen is changed. When changing screens, a user may be prompted toenter data not previously saved. Moreover, mandatory data fields may besupported for a software version.

The washing stations 100 a-x, a-y, a-j can be any type of cleaningequipment and are typically at different spatial locations in themonitored entity. Examples of washing stations include manual andautomated body member (e.g., hand, foot, etc.) and other object washingstations, such as automated hand washers, sinks/faucets and cleaningsolution dispensers, and the like. As will be appreciated, “object”refers to living or animate organisms, such as people and animals, aswell as inanimate objects or entities, such as equipment and tools.

As discussed below, each monitored entity 4804 a, b-w has acorresponding unique monitored entity identifier, and, within eachmonitored entity 4804 a, b-w, each washing station 100 a-x, a-y, a-j hasa unique station identifier. Accordingly, each pairing of monitoredentity and station identifiers is unique. In one configuration, anobject type identifier (not shown) is used in addition to the employeetype identifier. The object type identifier refers to animate andinanimate objects, each of which has a unique or substantially uniqueidentifier. While the identifier is carried removably by persons, theidentifier may be attached permanently or semi-permanently to theinanimate object. The identifier can be, for example, a passive RFIDtag, a bar code label, and the like. Unlike employee identifiers, which,for an enterprise, are unique, inanimate object identifiers may not beunique for each individual object in the enterprise but unique for aclass of objects of the same type. Thus, objects of the same type have acommon identifier, while objects of different types have differentidentifiers.

Each washing station 100 a-x, a-y, a-j includes a compliance module 316that in turn includes a processor and computer readable storage medium.The compliance module 316 identifies objects to be cleaned, determines asuitable cleaning protocol for the object to be cleaned, records objectidentifiers, object type identifiers, cleaning protocol identifiers,timestamps, compliance indicators, alert instances, and the like,determines the compliance or noncompliance of a cleaning, and generatesappropriate alerts. Additionally, each washing station 100 a-x, a-y, a-jcan further include modules to determine whether the operational statusof the corresponding washing station or a component thereof. As noted,the operational status includes not only whether the washing station ora component thereof is fully or partly operational or nonoperational,but also quantitatively a current level or remaining amount of aconsumable item, such as soap or a cleaning/antimicrobial solution, orqualitatively whether the consumable level falls below a thresholdlevel. Each module 316 may be associated with a memory 304 thattypically includes a record or lookup table listing, by employeeidentifier, a corresponding cleaning protocol identifier.

The compliance data hub 4812 generally collects, stores, and analyzescleaning information from the various administration computers 104 a,b-w. (The administration computers 104 a, b-w having collectedhand-washing data from the individual cleaning stations 100 a-x, a-y,a-j.) The compliance data hub 4812 includes a compliance server 4832 forreceiving cleaning information and forwarding the cleaning informationto an appropriate storage location in the compliance data hub 4812, andfor retrieving requested cleaning information from an appropriatestorage location and forwarding the information to an authorized andverified entity, such as compliance monitor 4816 a, b-p. In that regard,the compliance data hub 4812 further includes one or more databases 4836a-n for storing cleaning information and a Local Area Network 4840interconnecting the databases with the server 4832. The databases 4836a-n may be separate, as shown, with each database corresponding to amonitored entity 4804 a-n or a single database partitioned intosegments, one segment for each monitored entity 4804. The databases 4836a-n may be implemented using suitable database software (such as SQLServer Express).

The various administration computers 104 a, b-w associated with thevarious monitored entities may support modules that communicate withcompliance data hub 4812. In accordance with embodiments of the presentinvention, it may by necessary to import a license token from thecompliance data hub 4812 in order to enable modules used at theadministration computer level. The token may be specific to a particularenterprise and may include: the company name, a primary contact andprimary contact information, a secondary contact and secondary contactinformation, the number of licensed users, and the type of servicesupported. In accordance with embodiments of the present invention, thetoken may be an encrypted string of text that will be delivered as atoken license file. Moreover, the compliance data hub 4812 mayperiodically access and/or update modules at the administration computerlevel. In accordance with embodiments of the present invention, an emailmay be generated providing notice that a particular module was accessedor updated.

As shown in FIG. 48B, the compliance server 4832 includes a datamanagement module 4844 that queries administration computers 104 a,b-wfor cleaning information, forwards received cleaning information to anappropriate database 4836 for storage, receives requests for cleaninginformation and, after successful authentication and verification of therequest source, retrieves and forwards the requested cleaninginformation to the requesting source, and analyzes the cleaninginformation for instances of compliance and/or noncompliance events.

The data management module 4844 is operable to provide a data managementmodule report. An exemplary data management module report 1000 is shownin FIG. 49. The data management module report 4900 may include anenterprise identification number 4904. The compliance data hub 4812 mayassign a unique enterprise identification number 4904 to each businessenterprise monitored by the compliance data hub 4812. For example, theenterprise identification number 4904 having a value “123456”, as shownin FIG. 49, may be associated with the business enterprise 4806 shown inFIG. 48. A particular compliance data report 1000 may be provided inconnection with a particular business enterprise and will typically notinclude compliance data associated with other entities monitored by thecompliance data hub 4812. In particular, monitored entity 4804 w, whichis not part of business enterprise 4806, would be associated with adifferent enterprise identification number 4904. Accordingly, compliancedata associated with the monitored entity 4804 w would not appear on theexemplary compliance data module report shown in FIG. 49. The data hub4812 may maintain a contacts module operable to store and track contactinformation associated with each monitored business enterprise.

The data management module report 4900 may additionally include astation identification number 4908 and a user identification number4912. For a particular entry in the report 4900, the stationidentification number 4908 indicates the particular washing stationwhere the washing took place. The user identification number 4912 isassociated with a particular individual, such as an employee.Accordingly, for a particular entry in the report the useridentification number indicates who used the washing station. Each entryin the report 4900 includes a date 4916 and time 4920 indication whenthe washing took place. A facility identifier 4924 may also be includedif the monitored enterprise associated with the report 4900 includesmore than one location or facility. The facility identifier 4924 mayindicate in which facility within a particular enterprise the washingtook place. The report also includes an indication 4928 of whether ornot a complete wash cycle wash performed.

Additionally, the data management module report 4900 may include acompliance monitor identification number 4932. The compliance monitoridentification number 4932 may be used to indicate which compliancemonitor 4816 a, b-p of a plurality of compliance monitors 4816 a, b-p iscurrently receiving or will be receiving compliance data associated witha particular item in the data management module report 4900. In additionor in the alternative, the compliance monitor identification number 4932may be used by the compliance filter 4820 in connection with determiningwhich data items in the data management module report will be sent tothe compliance monitors 4816 a, b-p. It should be appreciated that aparticular report may include other fields not shown in FIG. 49. Forinstance, the report may include a wash station name or a wash stationIP address.

The exemplary data module report 4900, shown in FIG. 49, includesexemplary compliance statistics such as Boolean value indication ofwhether or not an individual identified by a particular user ID numbercompleted a hygiene requirement. Additionally, the report indicates thatthe individual is associated with a particular enterprise, i.e.,identified by a particular enterprise ID number. It should be understoodthat any of the compliance statistics discussed and described herein maybe provided in connection with a data management module report 4900. Inparticular, a data management module report 4900 may include time stampinformation, duration, date, percentage of hand washing statistics,current training segment statistics, allergy information, preferredentertainment content information. In embodiments of the presentinvention where location tracking is provided, a data management modulereport 4900 may include such hygiene protocol parameters as hygieneboundary transition information including time, date, level indications,hygiene radius violations, hygiene protocol violations, time to hygieneradius violation remediation, zone contamination statistics, hygieneradius downgrade statistics, time to hygiene downgrade information, timeto remediation of hygiene radius violations that occur as a result ofzone contamination. In embodiments of the present invention that includea complete hand care station, a data management module report 4900 mayinclude statistics such as compliance with daily hand washingrequirements, compliance with lotion use requirements and compliancewith mandatory wash chamber use requirements. In accordance withalternative embodiments of the present invention, a data managementmodule report 4900 may include graphical information such as thegraphical information presented in the bar chart 4500 and/or the linegraph chart 4600. In accordance with still alternative embodiments ofthe present invention, an interactive graphical user interface such asthe one shown in FIG. 47 may be included in a data management modulereport. In this embodiment, an individual who is monitoring hygienecompliance may actively monitor the current status of one or moreemployees by accessing graphical icons that represent the employees andthereby accessing drop down menus which provide real time informationindicating compliance with hygiene protocol requirements and/or currenthygiene status.

Data management module reports 4900 may be generated at different timeintervals and may be grouped based on different criteria. For example,reports 4900 may be generated daily, weekly, monthly, yearly, et cetera.Moreover, reports 4900 may be generated that are grouped by individual,company, facility, station, et cetera.

The compliance hub 4812 may allow particular individuals to accessstored data and/or reports including the data management module report4900. In accordance with embodiments of the present invention, a report4900 may be accessed remotely through a web interface. In that regard,web user 4848, with proper access permission, can access compliance datastored in the compliance data hub 4812. Particular individuals givenaccess to stored data may include, for example, company managers and/orofficers. As described in greater detail below, a report may be providedto a compliance monitor 4816 a, b-p.

Access to data management module reports 4900 and other stored data maybe limited and/or controlled by a security system. In that regard, thedata compliance hub 4812 may include a group security module thatprovides a password protected control to stored data. The level ofaccess allowed to a particular individual may be based on theirmembership in a particular group. Particular groups can include, forexample, account manager, customer, demo, administration, data hubadministration, and developer. Particular functions such as view, storeand print may be useable based on the level of access granted.

The compliance data hub 4812 can perform a variety of data processingfunctions. The compliance data hub 4832, for example, can comparecleaning information, or a given sensed parameter, to identify events,temporal trends, or differences and, if necessary, generate appropriatealarms. The alarms can be logged internally and/or forwarded to therespective cleaning station 100 a-x, a-y, a-j. The cleaning station 100a-x, a-y, a-j can then provide the alarm or warning to the appropriatecleaned object that, for instance, the cleaning provided was notcompliant. An exemplary alarm may be “Successful Cleaning”, “WarningCleaning Failed”, and the like. In another configuration, the alarm isthat a consumable level is low and requires replacement or that thewrong consumable is being used. The compliance data hub 4812 can alsoprovide communications to the cleaning stations. The communications can,for example, be audio and video information for display to users of thestations. As will be appreciated, the audio and video information may bestreaming media transmitted over the data network 4824, including, butnot limited to, video transmitted to video display 224.

In one configuration, the databases 4836 further include, or reference,information collected and stored by the enterprise security system (notshown). For example, employee badge activated entrances typicallycollect the badge identifier (or employee identifier) and a timestampwhen the badge identifier was received. Such information can be used inanalyzing compliance by determining whether the employer having thesensed badge identifier used the washing station in temporal proximityto passing through the secured entrance. As will be appreciated, thespatial locations of activated entrances and washing stations are knownand can be used, collectively, to monitor compliance.

The one or more compliance monitors 916 a, b-p may be, for example, anentity responsible for monitoring and/or otherwise administering thehygiene policies and/or requirements of the one or more enterprisesassociated with the monitored entities 904. The monitor may be agovernmental entity, such as a department of health and human servicesand the U.S. Food and Drug Administration, to name but a few, or aprivate entity such as a hygiene administration department. Typically, aplurality of compliance monitors 4816 a, b-p are involved, with eachmonitor being associated with a different local, state, or national(federal) government entity. By way of example, a facility of anenterprise 4806 may need to report compliance data to multiplecompliance monitors 4816 a, b-p, such as at the city or municipality,county, state, and federal levels.

In one or more embodiments of the present invention, a compliance filter4820 may be used. The compliance filter 4820, in one configuration,receives outgoing transmissions of cleaning information and filters theinformation before it is provided to one or more of the compliancemonitors 4816 a, b-p. The compliance filter 4820 may be part of orseparate from (as shown) the compliance data hub 4812. The compliancefilter 4820 ensures that cleaning information from different monitoredenterprises 4806 is not intermixed and only necessary cleaninginformation is provided to the compliance monitor 4816 a, b-p, therebyprotecting client/customer confidentiality and legally recognizedprivileges. In one configuration, the compliance filter 4820 is a lawfirm responsible for and knowledgeable about compliance monitoringrequirements. Attorneys may review the cleaning information and maintainthe confidentiality of the cleaning information under theattorney-client privilege. Furthermore, in at least one embodiment, thecompliance filter 4820 is an auditing entity other than a law firm.

The data network 4824 can be any circuit- or packet-switched network,with a packet-switched network, such as the Internet or World Wide Web,being preferred.

The cleaning information is typically converted into a selected form,packetized, and transmitted over the network 4824. The form of theinformation can be in accordance with any selected language, such as theeXtensible Markup Language or XML, the HyperText Markup Language orHTML, Remote Method Invocation or RMI, or Direct Socket Connections. Thepackets can be transported using any suitable protocol, such as theTransport Control Protocol/Internet Protocol suite of protocols, SimpleObject Access Protocol, or User Datagram Protocol.

An exemplary graphical user interface (“GUI”) for the compliance datahub 4812 will now be discussed. The GUI can be accessed from a washingstation 100, administration computer 4810, a compliance monitor 4816, orWeb browser (not shown) operated by a Web user 4848. A screen shot of aGUI page is shown in FIG. 53.

Referring to FIG. 53, GUI page 5300 includes home, reports, andadministrative tabs 5304, 5308, and 5312, respectively.

The home tab 5304 contains a (weekly) compliance dashboard 5316 thatreports up-to-date hand-washing statistics that can be viewed in variouschart forms, including compliance by department 5320 (shown), complianceby job title 5322, and quick reports 5323 tabs. In FIG. 53, thecompliance by department tab 5320 is selected, which produces a numberof tables of charts, namely daily departmental compliance 5324, NeonatalIntensive Care Unit compliance 5328, and my (current user) compliance5332. Although discussed as a weekly compliance dashboard, thecompliance dashboard can be determined over any suitable recurring timeperiod. The compliance-by-department chart 5336 offers comparative barcharts by department for the recurring time period (shown as being aweek). The vertical axis (height of the bars) reflects compliance bypercentage of set goals (which can vary by department). Departments areselected by a pull-down selector 5340 that offers the choice of “all” or“individual” department views. The departments shown in FIG. 53 are fora health care facility and include, in addition to NICU,anesthesiologist, cardiology, emergency room, geriatrics, intensive careunit (“ICU”), neurology, nutritional services, obstetrics, oncology,operating room, orthopedics, pharmacy, and radiology.

Referring to FIG. 54, the compliance by job title tab 5322 offerscomparative bar charts 5400 for job title for the last week. The jobtitles include administrator, food service, laboratory technician,licensed practical nurse (“LPN”), medical student, pharmacist,physician, physician assistant, radiologist, and registered nurse(“RN”). The vertical axis (height of the bars) reflects compliance bypercentage of set goals, which can vary by job title. Job titles can beselected through a pull-down selector 5404 that offers the choice of“all” or “individual” job-title views.

The quick reports tab 5323 displays all the report configurations thathave been saved from the compliance by department and compliance by jobtitle search boxes. Clicking on one of the displayed links will launchthe report with pre-configured parameters, with all the samefunctionalities a normally-generated report has.

A current washes quick reference 5344 takes the user directly to thecurrent washes section of the quick reports tab 5323. This providesinformation on all of the latest washes in the saved in the system forthat monitored entity.

Referring to FIG. 55, the daily compartment compliance chart 5324 breaksdown departmental compliance to a spreadsheet format. The table headersinclude department, target, washes, and compliance percentage (relativeto set goals, targets, or bench marks). To enhance readability, selectedrows may be color coded based on the department's compliance status. Forexample, green indicates greater than 90% of the target washes or goalhas been met. Yellow indicates that greater than or equal to 75% of thetarget washes has been met. Red indicates that less than 75% of thedaily departmental target washes have been met.

Referring to FIG. 56, the NICU compliance chart 5328 depicts dataspecific to a more important department (NICU) for the past reportingperiod (week). The dashed red line 5600 indicates target washes, and themoving blue line 5604 represents daily washes relative to the target forthe week of September 20 to September 26.

Referring to FIG. 57, the my (current user) compliance chart 5332depicts data specific to the active user for the past reporting period(week). The dashed red line 5700 indicates targeted washes, and themoving blue line 5704 represents daily washes relative to the target forthe week of September 20 to September 26.

Referring to FIG. 58, the reports tab 5308 provides three links, namelythe department compliance report 5800, the job-title compliance report5804, and the current washes report 5808. Referring to FIG. 59, thedefault state of the upper half of the department compliance report 5800is similar to the compliance by department chart in the GUI page 5300.The bottom portion of the screen has changed. It now contains a detailedcompliance information spreadsheet with columns, including department,date, number of employees, total target washes, and compliancepercentage. The show link 5904 permits the user to view the currentreport settings and parameters and edit them as desired. For example,the user can select a different set of departments, report period, andwhether the report format is to be in detail or summary form. The detailformat produces a report broken down by day. The summary form produces asummary report of all dates selected.

Referring to FIGS. 54 and 59, the upper half of the job title compliancereport 5900 looks similar to the job title compliance view in FIG. 54.The bottom portion of the screen shot has changed, and it now contains adetailed compliance information spreadsheet with the columns, job title,date, number of employees, total target, total washes and compliancepercentage. The show link 5904 permits the user to view the currentreport settings and parameters and edit them as desired. For example,the user can select a different set of job titles, different set ofdepartments (for which the job titles are to be reported (e.g.,physicians in the NICU), report period, and whether the report format isto be in detail or summary form, as discussed above.

The current washes report, which is also available from the quickreference 5344, displays all of the most recent washes in a detailedspreadsheet format. Displayed information includes user name, user'sdepartment, user's job title, user's employee identifier, user's badgeidentifier, the identifier of the wash station used, an indicatorwhether or not the wash was completed successfully, and the wash date.

The administrative tab 5312 permits administrators to manage variousfunctions, including washer configuration, user management (drop, add,or edit user information (e.g., user name, user contact information,user password, user employee identification number, user badge (or RFID)number, user assigned department, employee type identifier, user jobtitle, identities of devices associated with the user (e.g., a user workpiece, a door into or out of a designated user work area, a user poweredor unpowered tool, and the like), user shift times, and the like)),automated washing device management (e.g., add, drop, or edit deviceinformation (e.g., device or wash station name, device or wash stationlocation, device or wash station type, device or wash station assigneddepartment, device or wash station washes-per-soap bottle (currentlyremaining and/or original soap bottle capacity), a number of washesperformed by the device, a number of washes performed by the devicesince the soap bottle was replaced, device maximum wash watertemperature, device IP address, device IP port, and device serialnumber)), location management (setting up logical hierarchicalrelationships between locations), target management (e.g., edit thetarget number of washes per day for a department, job title, or user(the number of washes is of course a function of the number of hours therespective employee will work during the reporting period)), departmentmanagement (e.g., add, delete, or edit a department), job-titlemanagement (e.g., add, delete, or edit a job title), and shiftmanagement (e.g., add, delete, or edit a shift).

The operation of the hygiene monitoring system will now be discussedwith reference to FIG. 50.

In step 5000, the compliance module 316 of a selected washing station100 identifies an object within range of the sensor. For example, anRFID tag identifier code associated with an animate or inanimate objectis read by the RFID reader. Control then passes to step 5004.

In step 5004, the sensed identifier code and a first timestamp arerecorded by the module 316. The first timestamp is indicative of thestart time of the cleaning or washing cycle. In other configurations,the actual time that the cleaning cycle is commenced is sensed by asuitable sensor, such as an infrared sensor, motion sensor, or othertype of optical or electromagnetic sensor, and recorded.

In step 5008, the module 316 maps the sensed identifier code against thelookup table of FIG. 5B and determines, for the sensed identifier code,a corresponding value for the cleaning protocol to be employed. Themodule 316 then configures the corresponding washing station 100 forperforming the cleaning steps required by the protocol.

In step 5012, under the control of the module 316 the washing station100 cleans the identified object according to the requirements of thecleaning protocol. In one configuration, the washing station 100provides audible or visual instructions to the identified object or toan operator cleaning the identified object regarding the protocolrequirements and senses when the various protocol steps are performed.

In step 5016, the module 316 records the sensed identifier and a secondtimestamp when one or more steps of the cleaning protocol is/arecompleted or, if the cleaning protocol steps are not completed, when theobject to be cleaned is no longer within range of a sensor (e.g., theRFID reader or infrared sensor) of the washing station 100. The module316 further records, for the sensed identifier, the protocol identifierfor the corresponding protocol, and a compliance indicator (e.g.,whether the protocol was successfully or unsuccessfully completed beforethe sensed identifier left sensor range).

In step 5020, an appropriate alert is generated depending on whether theprotocol was successfully or unsuccessfully completed. The alert orwarning can be provided to the object by the washing station 100.

In one configuration, the response is based on one or more of the jobtitle, department, badge number, and/or employee identity of thenoncompliant user. Different employees may have different responses,depending upon one or more of their respective histories of complianceor noncompliance with a hygiene protocol, their respective job titles,their respective departments, their respective badge numbers, and/ortheir respective identities. A first user may thus have a first responsefor failing to complete a wash successfully, and a second user a seconddifferent response for failing to complete a wash successfully. Theresponse may be not only an audible and/or visual alert or warning butalso a selective disablement of a device associated with the user. Thedevice is identified in the user information. For example, a response toa first user failing to complete a wash successfully may be to disable afirst door to a first work area (such as a clean room, food storage orpreparation area, health care area, and the like) for the first user butnot a second door to a different second work area while a response to asecond different user failing to complete a wash successfully may notcause disablement of the first door but the second door because, forinstance, the second user, and not the first user, is not designated towork in the second work area. In another example, the first user, inresponse to failing to complete a wash successfully, may find a device,such as an oven, which the user uses in the course of his work, to bedisabled. In another example, the first user, in response to failing tocomplete a wash successfully, may be prevented from punching in on atime clock. In another example, a compliance monitor, in response to thefirst user failing to complete a wash successfully, alerts a responsibleperson (such as a manager or compliance administrator) other than thefirst user.

In decision diamond 5024, the module 316 determines whether collectedcompliance data or cleaning information should be uploaded to the datanetwork 4824 for transmission to the compliance server 4832. The triggerfor uploading the information could be, for example, time-based, basedon the number of washings performed by the corresponding station, orbased on the available or unavailable memory capacity of the module 316in the corresponding station. Alternatively, the trigger could be thereceipt of a request from the server 4832 for the information.

When the collected compliance data is to be provided to the server 4832,the module 316 generates one or more signals containing the data andincludes, in each signal, the monitored entity identifier of thecorresponding monitored entity (e.g., the identifier of the enterpriseoperating the washing station 100) and station identifier of the washingstation 100 performing the cleaning. As noted, the monitored entityidentifier is unique among the monitored entities, and the stationidentifier among the various stations 100 operated by the correspondingmonitored entity. The signal(s) are then forwarded to the complianceserver 4832.

The data management module 4844, based on the enterprise identifier,forwards the signals to the appropriate compliance database 4836, orstorage location(s), for storage and analysis. As will be appreciated,the module 4844 maps the monitored entity identifier against a lookuptable indexing monitored entity identifiers against database addressand/or storage address range. The received information is then forwardedto an interface for the corresponding database for storage. The table isfurther used to retrieve compliance data for an identified, monitoredentity.

In another embodiment, the data management module 4844 and/compliancefilter 4820 use location information to identify appropriate compliancemonitor(s) 4816 a, b-p to which to report, to configure collectionparameters, and/or to configure compliance reports for transmission tothe identified compliance monitor(s) 4816 a, b-p. The locationinformation can be in many different forms. For example, each monitoredfacility of a common enterprise or each monitored enterprise is assignedgeographical information indicating the physical location of themonitored entity. In another example, each monitored facility of acommon enterprise or each monitored enterprise is assigned geopoliticalinformation indicating the regulatory jurisdiction or political locationof the monitored entity. By way of illustration, the political locationof the facility would identify each compliance monitor 4816 a, b-p towhich activities at the facility must be reported. In yet anotherexample, each washing station is assigned geographic and/or geopoliticalinformation. In yet another example, each washing station has anembedded location module, such as a GPS or other satellite enabledlocating device, which provides location coordinates. In this example,as the washing station is moved from one facility to another thelocation information is changed dynamically.

Using the location information, whether associated with the facility asa whole or separately with each washing station in the facility, thedata management module 4844 determines the corresponding monitoring andreporting requirements for the pertinent compliance monitor(s) 4816 a,b-p. This is typically done using a lookup table, such as that shown inFIG. 51.

Referring to FIG. 51, the geographic location information 5100 is mappedagainst compliance monitor 5102, compliance data required 5104, requiredreporting frequency 5108, and reporting requirements 5112. Thegeographic location information 5100 refers to the expression ofgeographical and/or geopolitical location used to signify the locationof the monitored entity. As noted, the geographic location information5100 can be satellite-enabled location coordinates, compliance monitoridentifiers, city identifiers, county identifiers, state identifiers,country identifiers, and the like. The compliance monitor designation5102 identifies the compliance monitor 4816 a, b-p to which compliancereports are to be provided. The values in column 5102 can be valuesassociated with the compliance monitor 916 a, b-p (which may be anelectronic address). Compliance data required 5104 refers to theinformation to be collected to comply with requirements of theidentified compliance monitor. Compliance data required 5104 includes,for example, a number of required washes/station, percent compliance(determined on a suitable basis), number of required washes/employee,and the like. The required reporting frequency 5108 refers to howfrequently compliance data/reports are to be forwarded to the identifiedcompliance monitor. The frequency, for example, can be daily, weekly,monthly, yearly, and the like. Finally, report requirements 5112 referto requirements for the compliance information provided to theidentified compliance monitor. Report requirements 5112, for example,can refer to how the compliance data is to be transmitted to the monitor(e.g., by email, by mail, by upload/download operation over the datanetwork 4824, and the like), the formatting and organizationalrequirements for the report, the entities associated with the monitor towhom the information is to be provided and each entity's addressinformation, and the like. Other information in column 12 includeswhether the information is to be encrypted and, if so, what key(s) areto be employed, the human or computer language in which the report is tobe expressed (e.g., German, English, HTML, XML, and the like), and thelike.

The operation of this embodiment will now be discussed with reference toFIG. 52.

In step 5200, a scheduling module (not shown) generates an interruptidentifying one or more compliance monitors 916 a, b-p requiringcompliance report(s) to be provided. The interrupt is received by thedata management module 4844.

In step 5204, the module 4844 determines the location informationassociated with a selected one of the compliance monitors referenced inthe interrupt. This can be done by mapping an identifier of the selectedcompliance monitor against a listing of location information regulatedor serviced by the selected compliance monitor 486 a, b-p.

In step 5208, the module 4844 determines, based on the geographiclocation information 5100, each of the monitored entities 4804 a,b-wmonitored by the selected compliance monitor and, based on thegeographic location information 5100 a monitored entity identifier foreach of the identified entities, the compliance data required 5104.

In step 5212, the module 4844 retrieves the required compliance data.This is typically done iteratively on an enterprise-by-enterprise basisto avoid intermixing compliance data for different enterprises.Compliance data may be collected by querying the appropriate one of thefirst, second, . . . nth databases 4836 a-n and/or obtaining complianceinformation from each of the first, . . . xth washing stations 100 a-xat the subject facility for each identified enterprise.

In step 5216, the module 4844 determines the reporting requirements 5112for the selected compliance monitor.

In step 5220, the module 4844, using the reporting requirements andcompliance data obtained, generates and sends the report to thecompliance filter 4820 and/or directly to the compliance monitor 4816 a,b-p. When the report is sent to the compliance filter 4820, the filter4820 can remove unnecessary information collected by the washingstations and forward the filtered report to the compliance monitor 4816a, b-p.

In decision diamond 5224, the module 4844 determines whether theinterrupt identified a next compliance monitor. If not, control returnsto step 5200. If so, the next compliance monitor is selected, and themodule returns to step 5204.

The exemplary systems and methods of this invention have been describedin relation to automated cleaning systems. However, to avoidunnecessarily obscuring the present invention, the preceding descriptionomits a number of known structures and devices. This omission is not tobe construed as a limitation of the scope of the claimed invention.Specific details are set forth to provide an understanding of thepresent invention.
